K Previously, 6.6% of workers had a travel time to work of more than 60 minutes. An urban economist believes that the percentage has increased since then. She randomly selects 55 workers and finds that 10 of them have a travel time to work that is more than 60 minutes. Test the economist's belief at the x = 0.1 level of significance. What are the null and alternative hypotheses? Ho: ▼ versus H₁: (Type integers or decimals. Do not round.) Because npo (1-Po) (Round to one decimal place as needed.) Find the P-value. = 10, the normal model P-value= (Round to three decimal places as needed.) Is there sufficient evidence to support the economist's belief? 00 be used to approximate the P-value. OA. Yes, do not reject the null hypothesis. There is sufficient evidence because the P-value is greater than α. OB. No, do not reject the null hypothesis. There is not sufficient evidence because the P-value is greater than α. C. Yes, reject the null hypothesis. There is sufficient evidence because the…
The test statistic, t, is - 22.67. (Round to two decimal places as needed.) The P-value is 0.000. (Round to three decimal places as needed.) State the conclusion for the test. A. Reject the null hypothesis. There is sufficient evidence to support the claim that the cans of diet soda have mean weights that are lower than the mean weight for the regular soda. B. Fail to reject the null hypothesis. There is not sufficient evidence to support the claim that the cans of diet soda have mean weights that are lower than the mean weight for the regular soda. C. Fail to reject the null hypothesis. There is sufficient evidence to support the claim that the cans of diet soda have mean weights that are lower than the mean weight for the regular soda. D. Reject the null hypothesis. There is not sufficient evidence to support the claim that the cans of diet soda have mean weights that are lower than the mean weight for the regular soda.

n a sample of 1313 randomly selected high school seniors, the mean score on a standardized test was 11911191 and the standard deviation was 167.0167.0. Further research suggests that the population mean score on this test for high school seniors is 10201020. Does the t-value for the original sample fall between minus−t 0.99t0.99 and t 0.99t0.99? Assume that the population of test scores for high school seniors is normally distributed.

A coin was flipped 69 times and came up heads 39 times. At the .10 level of significance, is the coin biased toward heads? (a-1) H0: ππ ≤ .50 versus H1: ππ > .50. Choose the appropriate decision rule at the .10 level of significance. Reject H0 if z > 1.282 Reject H0 if z < 1.282 a b (a-2) Calculate the test statistic. (Carry out all intermediate calculations to at least 4 decimal places. Round your answer to 3 decimal places.) Test statistic (a-3) The null hypothesis should be rejected. False True (a-4) The true proportion is greater than .50. False True (b-1) Find the p-value. (Round your answer to 4 decimal places.) p-value (b-2) Is the coin biased toward heads? No Yes
In a population, the average IQ is assumed to be 120. To test this assumption a sample of 16 people is selected from this population. The average IQ of this sample is found to be 114 with a standard deviation of 20. Assuming that the IQ scores of the population are normally distributed, we want to test the claim (alternative hypothesis) that population mean is greater than 120. Find the t-value for this sample. You are not asked to do a hypothesis test in this problem. For this reason, level of significance is not given. You only need to find the t-value for the hypothesis test. In your answer, only 1 digit after the decimal will be enough. For example, your answer could be a number like -0.7 or 12.8. (So, the answer might be negative.) Wind
