Hypothesis Test - Population ProportionThe percentage of Texans not covered by health care insurance in 2019 was 15%. Let p denote the proportion of those not covered by health care insurance in Texas. We would like to test the hypotheses H₀ : p ≤ 0.15 vs. Ha : p > 0.15 using a random sample of 100 Texans. The percentage of those who do not have health care insurance in the sample is 20%. What is the value of the test statistic? 0.95 1.4 1.25 2.25

Computing the Z-test Statistic The State College is evaluating a new English composition course for freshmen. A random sample of n = 25 freshmen is selected from the State College. All 25 students are placed in the new English composition course during their first semester. One year later, a writing sample is obtained for each student and their writing samples are graded using a standardized evaluation technique. The average score for the sample is M= 76. For the general population of the State College, writing scores form a normal distribution with a mean = 70 and a standard deviation = 20. Please calculate the appropriate hypothesis test using all four steps?
Modeling Clinical Trials 1 punto posible (calificable) In a clinical trial, a pharmaceutical company wants to determine the efficacy of a cold remedy. To do so, they recruit 2n individuals to participate in a study, (randomly) placing n individuals in the treatment group and n individuals in the control group. Throughout the study, the treatment group will receive the actual drug, while the control group will only receive a placebo (for example, a sugar pill). To statistically model this scenario, we let X1,..., Xn be random variables that denote the number of coughs per hour of individuals 1,..., n, respectively in the treatment group, and • Y1,..., Yn be random variables that denote the number of coughs per hour of individuals 1,..., n, respectively, in the control group. Let's assume that the individuals participating in the trial are separated throughout the trial, so that it's reasonable to expect the coughs per hour of one individual in the study will not affect the coughs per…
