**Hypothesis Test**It is conjectured that the proportion of all people who went trick-or-treating and also had a pumpkin carved into a jack-o'-lantern at their home is 0.62. Of interest is to test this claim versus the alternative that the proportion of all people who went trick-or-treating and also had a pumpkin carved into a jack-o'-lantern at their home is less than 0.62.A simple random sample of 270 people who went trick-or-treating is selected, and 162 of them also had a pumpkin carved into a jack-o'-lantern at their home (and the other 108 did not). If appropriate, use this information to test if the proportion of all people who went trick-or-treating and also had a pumpkin carved into a jack-o'-lantern at their home is less than 0.62 at the α = .10 level of significance.**Which of the following provides both the correct null and the correct alternative hypothesis for this situation?**- [ ] H0: π = 0.62; Ha: π < 0.62- [ ] H0: π = 0.71; Ha: π < 0.71- [ ] H0: π = 0.62; Ha: π < 0.62- [ ] H0: π = 0.71; Ha: π < 0.71- [ ] H0: π = 0.58; Ha: π > 0.58- [ ] H0: π > 0.62; Ha: π < 0.62

A golf instructor claims that more than 70% of his students have improved their driving distance by at least 20 yards after viewing and applying the techniques described in his instructional video. If 138 out of 180 viewers say that their driving distance has improved by at least 20 yards, is the instructor's claim valid? Identify the null and alternative hypotheses for this scenario. Is the instructor's claim that "more than 70% of his students have improved their driving distance by at least 20 yards," valid? Your response should include your decision and conclusion in context of the scenario.
Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC bookstore costs $ 93.16. You want to test this claim.

2. Forty-five percent of the entering CSUN freshmen in Fall 2019 were proficient in math. www.csun.edu/counts/new_first_time_freshman.php a. You want to see if the percentage is different for this fall's entering freshmen. Your hypotheses are Ho: На: where p stands for the percentage of freshmen who were proficient in Fall 2019 / this fall. b. Suppose that the null hypothesis is true that the percentage is 45% for this fall. Here is the sampling distribution of the values of p that would be expected if you repeatedly took random samples of 150 freshman entering this fall and found the proportion proficient in math. From the sketch alone, estimate the mean and the SE 0.33 0.37 0.41 0.45 0.49 0.53 0.57 If the null hypothesis is true, would it be unusual to get 50% in your sample who were proficient in mathematics?
