6. In a survey of 2563 adults from France, 1666 said that they believed that the activities of humans are contributing to an increase in global temperatures. A 95% confidence interval for the proportion p of adults in France, who thinks humans are contributing to an increase in global temperatures, is closest to (a) (0.3815, 0.4227) (b) (0.5315,0.7935) (c) (0.6315, 0.6685) (d) (0.1727,0.7819) (e) (0.2500, 0.7500)

10) The average height of males in the freshmen class of a certain college has been 68.5 inches. Is there a reason to believe that there has been no change in the average height if a random sample of 50 males in the present freshmen class has an average height of 69.7 inches with a standard deviation of 2.7 inches? Use a 0.01 level of significance. Solution: I. Statement of the Hypothesis: Но H1 II. Statistical Test: III. Level of Significance and Critical Value: IV. Computed value of Z: V. Conclusion:

A sample of n=25 individuals is randomly selected from a population with a mean of p=65, and a treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be 70. If the sample standard deviation is s=20, what is the value of your tusing a two-tailed test with alpha level of 0.05? О а. 2.5 O b. 1.0 О с. 1.5 O d. 2.0
Consider a drug testing company that provides a test for marijuana usage. Among 294 tested subjects, results from 28 subjects were wrong (either a false positive or a false negative). Use a 0.05 significance level to test the claim that less than 10 percent of the test results are wrong. Identify the null and alternative hypotheses for this test. Choose the correct answer below. О А. Но: р0.1 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is- (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is. (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. O A. Fail to reject Ho. There is sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong. O B. Fail to reject Hn. There is not sufficient evidence to warrant support of the claim that less than 10 percent of the test results are…
1. A simple random sample of the weight of 19 green M&Ms has a mean of 0.8635 grams. Assume that o is known to be 0.0565 grams. Use a 0.05 significance level to test the claim that the mean of all green M&Ms is equal to 0.8535 grams. Do green M&Ms appear to have weights consistent with the package label? Claim: Но: Vs. Hạ: Test statistic to use: Tail of the distribution: Reject Ho if Computation: Decision: Conclusion:

The mean number of eggs per person eaten in the United States is 266. Do college students eat a different number of eggs than the average American? The 61 college students surveyed averaged 285 eggs per person and their standard deviation was 72.6. What can be concluded at the a= 0.10 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Но: v Select an answer H.: vSelect an answer c. The test statistic ? (please show your answer to 3 decimal places.) d. The p-value = e. The p-value is ? f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... (Please show your answer to 4 decimal places.) a O The data suggest that the sample mean is not significantly different from 266 at a = 0.10, so there is statistically insignificant evidence to conclude that the sample mean number of eggs consumed by college students per year is different from 285. O The data suggest that the…
An online food delivery service in metro manila claims that the delivery time is not greater than 30 minutes with a standard deviation of 3 minutes. But a certain customer opposed the claim and found that the average time in the past 31 delivery services is 40 minutes. Perform a hypothesis testing with a = 0.10 to see if the claim is correct. 1.
