SAMPLE DATA
under 65
no hypertension-192
hypertension-48
65 and over
no hypertension-25
hypertension-35
Use the sample data to find a point estimate for the population proportion of adults under 65 with hypertension, ?1, and the point estimate for the population proportion of adults 65 and over with hypertension, ?2. Express your answers with three decimal places.
d. Test the claim, at the 1% significance level, that the proportion of adults under 65
with hypertension is less than the proportion of adults 65 and over with
hypertension.
e. Test the claim from part d. by writing all five steps of the hypothesis test. Use the
critical value method and refer to the values calculated from Excel. From the
sample data, can you conclude that the proportion of adults under 65 with
hypertension is less than the proportion of adults 65 and over with hypertension?

- Pain medications sometimes come with side effects. One side effect is dizziness. A researcher wanted to determine if some pain medications produced more or less dizziness than others. The results from his study are shown in the table below. Use a test to determine if the proportion of people within each treatment group who experienced dizziness are the same at the � = .01 level of significance. Tordol Placebo Naproxen Tylenol Advil Dizziness 83 32 36 5 8 No dizziness 4063 1832 1330 382 337 1) Determine the null and alternative hypotheses.

- ou are doing a problem where you have a negative z-score, and you have to look up the proportion of the shaded area in the tail beyond that z-score; in other words, you are shading to the left from your z-score, and looking for the proportion that you shaded. Four “proportions” are given below. Which one is the ONLY one that could potentially be the number you are looking for? (Hint: Think about what you know about proportions: What kind of number are they? And what things can they represent?)

Similarly, 177 out of 1213 citizens of country B reported being foreign-born. The researchers want to test if the proportions of foreign born are the e in country B as in country A. Complete parts a through c below. What is the difference in the sample proportions, p, - p2, of foreign born residents from both countries? Assume p, is the proportion of foreign born residents from country A and p, is the proportion of foreign born residents from country B. difference in the sample proportions, p1-P2, is und to three decimal places as needed )arrow_forward
