### Hypothesis Testing Guide**Consider the hypothesis test below.**\[H_0: p_1 - p_2 \leq 0\]\[H_a: p_1 - p_2 > 0\]The following results are for independent samples taken from the two populations.#### Sample Information- **Sample 1** - \( n_1 = 100 \) - \( \bar{p}_1 = 0.29 \)- **Sample 2** - \( n_2 = 300 \) - \( \bar{p}_2 = 0.13 \)**Use pooled estimator of \( p \).**---### Questions**a. What is the p-value (to 4 decimals)?** Use Table 1 from [Appendix B](#).**b. With \( \alpha = 0.05 \), what is your hypothesis testing conclusion?**- [ ] **Select your answer** (dropdown menu with options to conclude)---This exercise involves performing a hypothesis test with unequal population proportions using the pooled estimator method. You will calculate the p-value and discuss your conclusion based on a significance level of 0.05.

Kenneth, a competitor in cup stacking, claims that his average stacking time is 8.2 seconds. During a practice session, Kenneth has a sample stacking time mean of 7.8 seconds based on 11 trials. At the 4% significance level, does the data provide sufficient evidence to conclude that Kenneth's mean stacking time is less than 8.2 seconds? Accept or reject the hypothesis given the sample data below. H0:μ=8.2 seconds; Ha:μ<8.2 seconds α=0.04 (significance level) z0=−1.75 p=0.0401 Select the correct answer below: a. Do not reject the null hypothesis because the p-value 0.0401 is greater than the significance level α=0.04. b. Reject the null hypothesis because the p-value 0.0401 is greater than the significance level α=0.04. c. Reject the null hypothesis because the value of z is negative. d. Reject the null hypothesis because |−1.75|>0.04. e. Do not reject the null hypothesis because |−1.75|>0.04.
Two possible p-values are given. Which one provides the strongest evidence against H0? p -value=0.5 p-value=0.06
Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error.
