A poll of 1088 teens aged 13 to 17 showed that 52% of them have made new friends online. Use a 0.10 significance level to test the claim that half of all teens have made new friends online. Use the P-value method. Use the normal distribution as an approximation to the binomialdistribution. Let p denote the population proportion of all teens aged 13 to 17 who have made new friends online. Identify the null and alternative hypotheses.Ho: PH₁: p(Type integers or decimals. Do not round.)Identify the test statistic.2=(Round to two decimal places as needed.)Identify the P-value.P-value=(Round to three decimal places as needed.)State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim.the null hypothesis. There ▼ sufficient evidence tothe claim that half of all teens have made new friends online.

We have given information with the usual notation, n=1088, p^=52% The level of significance is…

The average final exam score for the statistics course is 78%. A professor wants to see if the average final exam score for students who are given colored pens on the first day of class is higher. The final exam scores for the 13 randomly selected students who were given the colored pens are shown below. Assume that the distribution of the population is normal. 90, 84, 93, 77, 95, 79, 82, 70, 85, 70, 83, 100, 90 What can be concluded at the the a = 0.05 level of significance level of significance?
In 1992 a national vital statistics report indicated that about 2.3% of all births produced twins. Is the rate of twin births the same among very young mothers? Data from a large city hospital found only 7 sets of twins were born to 455 teenage girls. Test an appropriate hypothesis and state your conclusion. Be sure the appropriate assumptions and conditions are satisfied before you proceed. Are the assumptions and the conditions to perform a one-proportion z-test met? ... No Yes State the null and alternative hypotheses. Choose the correct answer below. A. Ho: p=0.023 HA: P >0.023 B. Ho: p=0.023 HA: P = 0.023 C. Ho: p=0.023 HA: P<0.023 D. The assumptions and conditions are not met, so the test cannot proceed. Determine the z-test statistic. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. Z= (Round to two decimal places as needed.) OB. The assumptions and conditions are not met, so the test cannot proceed.

A television show conducted an experiment to study what happens when buttered toast is dropped on the floor. When 49 buttered slices of toast were dropped, 28 of them landed with the buttered side up and 21 landed with the buttered side down. Use a 0.01 significance level to test the claim that toast will land with the buttered side down 50% of the time. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution. After that, supposing the intent of the experiment was to assess the claim that toast will land with the buttered side down more than 50% of the time, write a conclusion that addresses the intent of the experiment.
The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject. Ho when the level of significance is (a) a = 0.01, (b) a = 0.05, and (c) a=0.10. P=0.0411 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? OA. Fail to reject Ho because the P-value, 0.0411, is greater than a = 0.01. OB. Fail to reject Ho because the P-value, 0.0411, is less than a =0.01. OC. Reject Ho because the P-value, 0.0411, is greater than a = 0.01. OD. Reject Ho because the P-value, 0.0411, is less than a = 0.01 (b) Do you reject or fail to reject Ho at the 0.05 level of significance? O A. Reject Ho because the P-value, 0.0411, is greater than a = 0.05. OB. Fail to reject Ho because the P-value, 0.0411, is less than a = 0.05. OC. Fail to reject Ho because the P-value, 0.0411, is greater than a = 0.05. O D. Reject Ho because the P-value, 0.0411, is less than a = 0.05. CECO
A researcher completes a hypothesis test using a = .05. Based on the evidence from the sample, the researcher decides to reject the null hypothesis. Which statement below is true? a. The researcher might have made a Type I error, but the probability is less than 5%. b. The researcher might have made a Type II error. c. The researcher might have made a Type I error, but the probability is less than 10%. d. The researcher has made the correct decision.
A poll of 1081 Americans showed that 46.8% of the respondents prefer to watch the news rather than read or listen to it. Use those results with a 0.05 significance level to test the claim that fewer than half of Americans prefer to watch the news rather than read or listen to it. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution.

Describe the type I error. Choose the correct answer below. 16 OA. A type I error will occur when the actual proportion of new customers who return to buy their next pair of shoes is at least 0.25, but you reject Ho: p≥ 0.25. B.

A type I error will occur when the actual proportion of new customers who return to buy their next pair of shoes is at least 0.25, but you fail to reject Ho: p≥ 0.25. D. A type I error will occur when the actual proportion of new customers who return to buy their next pair of shoes is no more than 0.25, but you reject Ho: p≤0.25. Describe the type II error.

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject H, when the level of significance is (a) a = 0.01, (b) a = 0.05, and (c) a = 0.10. P=0.0212 (a) Do you reject or fail to reject H, at the 0.01 level of significance? O A. Fail to reject H, because the P-value, 0.0212, is greater than a= 0.01. O B. Reject H, because the P-value, 0.0212, is greater than a = 0.01. OC. Reject H, because the P-value, 0.0212, is less than a = 0.01. O D. Fail to reject H, because the P-value, 0.0212, is less than a = 0.01. (b) Do you reject or fail to reject H, at the 0.05 level of significance? O A. Fail to reject H, because the P-value, 0.0212, is greater than a= 0.05. O B. Reject H, because the P-value, 0.0212, is greater than a = 0.05. OC. Fail to reject H, because the P-value, 0.0212, is less than a = 0.05. O D. Reject H, because the P-value, 0.0212, is less than a = 0.05. (c) Do you reject or fail to reject H, at the 0.10 level of significance? O A. Reject H, because…
Suppose you conduct a hypothesis test based on a sample where the sample size is n = 50, and arrive at a p-value of 0.08. You then refer back to your notes and discover that you made a careless mistake, the sample size should have been n = 500. Will your p-value increase, decrease, or stay the same? stay the same increase decrease Answer not here
