The one-sample -statistic for a test of Ho: 4 = 42 versus H, : I < 42 based on n = 15 observations has the value § 1 = - 1.343, where Ho and H are the null and alternative hypotheses, respectively. The sample size is denoted by n. cmillan Use this 1-table to determine which two P-values bracket the P-value of the test. Report your answers in decimal form as © Ma listed in the t-table.

Please answer all parts You are conducting a study to see if the proportion of voters who prefer Candidate A is significantly different from 75% at a significance level of αα = 0.10. According to your sample, 47 out of 58 potential voters prefer Candidate A. For this study, we should use The null and alternative hypotheses would be: H0H0: (please enter a decimal) H1H1: (Please enter a decimal) 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 αα Based on this, we should the null hypothesis. As such, the final conclusion is that ... The sample data suggest that the population proportion is not significantly different from 75% at αα = 0.10, so there is not sufficient evidence to conclude that the proportion of voters who prefer Candidate A is different from 75%. The sample data suggest that the…

lume Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. A safety administration conducted crash tests of child booster seats for cars. Listed below are results from those tests, with the measurements given in hic (standard head injury condition units). The safety requirement is that the hic measurement should be less than 1000 hic. Use a 0.05 significance level to test the claim that the sample is from a population with a mean less than 1000 hic, Do the results suggest that all of the child booster seats meet the specified requirement? 712 660 1192 616 588 534 O What are the hypotheses?
If we have a sample size of 100 from a population of rope with sample mean breaking strenfgth of 1040 pounds with standard deviation 200 pounds and we wish to run a hypothesis test with this data to see if the population mean breaking strength exceeds 1000 pounds, then what is the TYPE 1 ERROR
Suppose the number of observations in a sample is 30, sample mean is 73 and sample standard deviation is 13. Perform a test of null hypothesis is `population mean is equal to 72` and the alternative hypothesis is `population mean is greater than 72`. (Use 5% significance level) a) 0.42: accept the null b) -0.42: reject the null c) 0.25: accept the null d) -0.25: reject the null
A random sample of 64 students from Wharton School was taken and their GPA were recored. The sample mean GPA was 2.8 and the sample standard deviation was 0.5. The population size is 1200. a) Test at %5 significance level that null hypothesis being the population mean GPA is equal to 2.7 against the alternative it is not equal to 2.7. Suppose that population standard deviation is known to be 0.3 for this question. b) Compute the p-value c)Draw the figure showing the areas of Type 1 error, Type 2 error and p- value (it is not necessary to finde Type 2 error.)

webassign.net/web/Student/Assignment-Responses/submit?pos=10&dep=22704121&tags=autos A newspaper infographic titled "Social Media Jeopardizing Your Job?" summarized data from a survey of 1,825 recruiters and human resource professionals. The infographic indicated that 53% of the people surveyed had reconsidered a job candidate based on his or her social media profile. Assume that the sample is representative of the population of recruiters and human resource professionals in the United States. (a) Use the given information to estimate the proportion of recruiters and human resource professionals who have reconsidered a job candidate based on his or her social media profile using a 95% confidence interval. (Use a table or technology. Round your answers to three decimal places.) Give an interpretation of the interval in context. There is a 95% chance that the true proportion of recruiters and human resource professionals who have reconsidered a job candidate based on his or her social…
