In a sample of 57 men, 35 said that they had less leisure time today than they had 10 years ago. In a sample of 57 women, 43 women said that they had less leisure time today than they had 10 years ago. At \(\alpha = 0.10\), is there a difference in the proportions?Use \(p_1\) for the proportion of men with less leisure time.**Part: 0 / 6**---**Part 1 of 6**State the hypotheses and identify the claim with the correct hypothesis.\[ H_0: \] (Choose one) \[ H_1: \] (Choose one) This hypothesis test is a (Choose one) test.**Diagram Explanation:**There are several icons with mathematical symbols indicating options for hypothesis testing. These include:- \(<\)- \(\leq\)- \(>\)- \(\geq\)- \(=\)- \(\neq\) These options are likely used to define and test the null and alternative hypotheses for the given scenario.

Solution-: Let, p1 - be proportion of men with less leisure time and p2 - proportion of women with…

The average amount of time it takes for couples to further communicate with each other after their first date has ended is 2.35 days. Is this average different for blind dates? A researcher interviewed 70 couples who had recently been on blind dates and found that they averaged 2.5 days to communicate with each other after the date was over. Their standard devlation was 0.655 days. What can be concluded at the 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: Ho: ?v Select an answerv H: ?vSelect an answerv c. The test statistic ?v (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ?v a f. Based on this, we should Select an answerv the null hypothesis. g. Thus, the final conclusion is that ...

You are a process engineer for a company that manufactures widgets. A particular machine at your company has some downtime during the day on 36.5% of days. You decided to make some changes to how the machine is calibrated in an attempt to reduce downtime. 63 days after your changes were implemented, you find that the machine had some downtime during the day on 31.0% of days. Conduct a hypothesis test to determine if the proportion of days that the machine has downtime has decreased from before, with a= 0.1. * Using this information, what is the p in your analysis? Note: 1- Only round your final answer. Enter your final answer with 2 decimal places.

Life on Other Planets Forty-five percent of people believe that there is life on other planets in the universe. A scientist does not agree with this finding. He surveyed 110 randomly selected individuals and found 66 believed that there is life on other planets. At α=0.05, is there sufficient evidence to conclude that the percentage differs from 45? Use the P-value method with a graphing calculator. State the hypotheses and identify the claim with the correct hypothesis.
