Question A medical billing specialist claims that the proportion of ER patients who do not have health insurance is different than 0.58. If the medical specialist wants to conduct a hypothesis test, should they use a left-, right, or two-tailed hypothesis test to analyze whether the proportion of ER patients who do not have health insurance is different than 0.58? Select the correct answer below:
Clinical Trials Researchers at Yale University conduct a wide variety of clinical trials by using subjects who volunteer after reading advertisements soliciting paid volunteers.

MORE BENEFITS OF EATING ORGANIC Using data from a study, we find a significant difference in the proportion of fruit flies surviving after 13 days between those eating organic potatoes and those eating conventional (not organic) potatoes. This exercise asks you to conduct a hypothesis test using additional data from this study. In this case, we are testing where p, and p, represent the proportion of fruit flies alive at the end of the given time frame of those eating organic food and those eating conventional food, respectively. We have n₁ = n₂ = 500. Show all remaining details in the test, using a 5 % significance level. Effect of Organic Raisins After 20 Days After 20 days, 275 of the 500 fruit flies eating organic raisins are still alive, while 170 of the 500 eating conventional raisins are still alive. ¹Proportions approximated from information given in the paper.

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
