(a) Compute the sample proportion p. Round the answer to at least three decimal places. The sample proportion is Part: 1/ 4 Part 2 of 4 (b) Are the assumptions for a hypothesis test satisfied? Explain. (Choose one) the number of individuals in each category is smaller than 10. greater than smaller than rart 3 o1 4 (c) It is desired to test Ho:p=0.5 versus H :p>0.5. Compute the test statistic z. Round the answer to at least two decimal places. The test statistic is

Test the claim that the proportion of men who own cats is significantly different than 50% at the 0.02 significance level.a.) The null and alternative hypothesis would be: b.) The test is: right-tailed left-tailed two-tailed   Based on a sample of 60 men, 59% owned cats   c.) The sample proportion ˆp=d.) The test statistic is:  (to 2 decimals)e.) At α=α=0.02, the critical value is:±  (to 2 decimals)f.) Based on this we: Reject the null hypothesis Fail to reject the null hypothesis

Q-3) Show all the steps for the problem.

(2) Choose the one alternative that best completes the statement or answers the question. Assume two independent random samples are available which provide sample proportions. For the first sample assume n₁ = 100 and x₁= 39. For the second sample, assume n₂= 100 and x₂= 49. Test the null hypothesis that the population proportions are equal versus the alternative hypothesis that the proportions are not equal at the 90% confidence level. Frame the test statistic by subtracting the proportion for population 1 from that for population 2. Pick an appropriate z value, p-value and conclusion. Round your answer to the nearest thousandth. Note that this is a two- tailed test. z-value = -1.425 p-value= 0.077 statistically significant z-value = 1.425 p-value= 0.077 statistically significant z-value = -1.425 p-value= 0.077 not statistically significant z-value = 1.425 p-value= 0.154 statistically not significant

The researchers found that 83.3% of students in the sample have rarely or never used the food pantry on campus. We will test whether it is plausible that more than 80% of all students on campus have rarely or never used the campus food pantry. Identify (describe in words) the parameter and include the appropriate symbol. State the null and alternative hypotheses in symbols.     Use the One proportion inference applet to create a distribution of 1000 simulated sample statistics (with the “Proportion of successes” option) and include a screenshot below that shows what you entered in the applet as well as the resulting distribution. Check the Summary Statistics box and explain why the values of the mean and SD (SE) make sense according to theory-based methods.   Use the applet to find a p-value for this situation. Explain how you do this, and include a screenshot that shows the relevant portion of the applet, including the distribution of simulated sample statistics. State the value of…

Test the claim about the population variance o² at the level of significance a. Assume the population is normally distributed. Claim: o² ≤17.1; x = 0.01 Sample statistics: s² = 25.13, n = 41 Write the null and alternative hypotheses. Ho: H₂:0²
