5. A test of Ho: 10 vs. Ha: < 10 is conducted based on a random sample of 15 observations.Assume that the conditions for inference have been met. What does it mean to use a significancelevel of α = 0.05 for the test?(A) The test procedure would result in an incorrect decision for 5% of all possible random samplesof 15.(B) If <10, the test procedure would result in a correct decision for 5% of all possible randomsamples of 15.(C) If μ < 10, the test procedure would result in an incorrect decision for 5% of all possible randomsamples of 15.(D) If μ = 10, the test procedure would result in a correct decision for 5% of all possible randomsamples of 15.(E) If µ = 10, the test procedure would result in an incorrect decision for 5% of all possible randomsamples of 15.

In a hypothesis test, we have two competing hypotheses: the null hypothesis (H0) and the alternative…

The following data are the daily number of minutes of smartphone use for a random sample of 8students at your institution: 117, 156, 89, 72, 116, 125, 101, 100.(You may use t(df=7, 0.05) = -1.895) (a) Test the null hypothesis according to which the true mean is greater or equal to 100 minagainst the alternative that it is less than 100. Use a significance level of 5% (state the test statistic and the conclusion).
The proportion P residence in a community recycles traditionally been 70%. Policymaker claims of the unfortunate less than 70% now that one of the recycling centers has been relocated. It's 137 out of a random sample of 205 residence in the community said they recycle, is there enough evidence to support the policy makers claim at the 0.05 level of significance?
1) If your p-value is less than a significance level , then your decision is to fail to reject the null hypothesis. True or False 2)The test statistic, z, in a hypothesis test measures the difference between the sample proportion and the hypothesized proportion in terms of standard deviations. True or False
A hospital reported that the normal death rate for patients with extensive burns (more than 40% of skin area) has been significantly reduced by the use of new fluid plasma compresses. Before the new treatment, the mortality rate for extensive burn patients was about 60%. Using the new compresses, the hospital found that only 44 of 93 patients with extensive burns died. Use a 1% level of significance to test the claim that the mortality rate has dropped. A) What is the value of the sample test statistic? (Round your answer to two decimal places.) B) what is the P value C) Will you reject or fail to reject the null hypothesis

The average retirement age in America is 66 years old. Do small business owners retire at an older average age? The data below shows the results of a survey of small business owners who have recently retired. Assume that the distribution of the population is normal. 63, 74, 59, 64, 74, 60, 71, 67, 65, 70, 63 What can be concluded at the the � = 0.05 level of significance level of significance? For this study, we should use The null and alternative hypotheses would be: �0: �1: The test statistic = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is � Based on this, we should the null hypothesis. Thus, the final conclusion is that ... The data suggest the populaton mean is significantly older than 66 at � = 0.05, so there is sufficient evidence to conclude that the population mean retirement age for small business owners is older than 66. The data suggest…
A physical therapist wants to determine the difference in the proportion of men and women who participate in regular sustained physical activity. What sample size should be obtained if she wishes the estimate to be within five percentage points with 95% confidence, assuming that (a) she uses the estimates of 22.9% male and 19.5% female from a previous year? (b) she does not use any prior estimates?
37. A significance test is conducted using z procedures. When the test statistic is analyzed using one-sided procedures, it is significant at the a = 0.05 level but not the a = 0.01 level. Which of the following must be true about the test statistic if the analysis is conducted with a two-sided procedure? (A) Significant at the a = 0.01 level but not at the a = 0.10 level (B) Significant at the a= 0.10 level but not at the a = 0.01 level %3D (C) Significant at the a= 0.10 level but not at the a = 0.05 level (D) Significant at the a = 0.05 level but not at the a = 0.10 level (E) Significant at the a = 0.025 level but not at the a = 0.005 level %3D
You wish to test the following claim (H) at a significance level of a = 0.005. For the context of this problem, Hd = H2 - H1 where the first data set represents a pre-test and the second data set represents a post-test. H.: Ha = 0 H.: Ha + 0 You believe the population of difference scores is normally distributed, but you do not know the standard deviation. You obtain pre-test and post-test samples for n = difference (post - pre) is d 15 subjects. The average = 32.6 witha standard deviation of the differences of 31.6. || What is the critical value for this test? (Report answer accurate to three decimal places.) critical value = ± What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = The test statistic is... O in the critical region O not in the critical region This test statistic leads to a decision to...

5. It is claimed that the proportion of high school athletes who go on to play sports in college is 0.08. Believing this claimed value is incorrect, a researcher surveys a random sample of former high school athletes and finds that the proportion who went on to play sports in college is 0.07. When a hypothesis test is conducted at a significance (or alpha) level of 0.10, the P-value is found to be 0.06. What decision should the researcher make based on the results of the hypothesis test? 1. The null hypothesis should be rejected because 0.06 is less than 0.10. 2. The null hypothesis should be rejected because 0.06 is less than 0.07. 3. The null hypothesis should be rejected because 0.06 is less than 0.08. 4. The null hypothesis should be rejected because 0.07 is less than 0.08. 5. The null hypothesis should not be rejected.
We want to know if there is a difference between the mean list price of a three bedroom home, μ3, and the mean list price of a four bedroom home, μ4, H0:μ3=μ4 versus Ha:μ3≠μ4. Suppose we get a p-value of 0.1325, which is the proper conclusion of this test? a) We accept the null hypothesis at 5% significance. There is extremely strong evidence of a significance difference between the mean list price of three bedroom homes and the mean list price of four bedroom homes. b) We reject the null hypothesis at 5% significance. There is no evidence of a significance difference between the mean list price of three bedroom homes and the mean list price of four bedroom homes. c) We fail to reject the null hypothesis at 5% significance. There is no evidence of a significance difference between the mean list price of three bedroom homes and the mean list price of four bedroom homes. d) We reject the null hypothesis at 5% significance. There is extremely strong evidence of a significance difference…

For the context of this problem, d = 2-1 where the first data set represents a pre-test and the second data set represents a post-test. Ho: Pd = 0 Ha: d < 0 You believe the population of difference scores is normally distributed, but you do not know the standard deviation. You obtain pre-test and post-test samples for n = 301 subjects. The average difference (post-pre) is d = 2.4 with a standard deviation of the differences of sa = 22.7. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = L What is the P-value for this test? (Report answer accurate to four decimal places.) P-value = The P-value is... O less than (or equal to) a O greater than a This P-value leads to a decision to... O reject the null O accept the null O fail to reject the null
