Question

A researcher is interested in determining whether a new drug lowers blood pressure more than a leading drug. The average systolic blood pressure was analyzed for 10 people using the drugs. The mean systolic blood pressure of the people using the new drug is 121.7 millimeters of mercury whereas the mean systolic blood pressure for those using the leading drug was 123.1 millimeters of mercury. After rerandomizing the data 100 times, the following dot plot was generated.
Hint: where SD is the standard deviation, XH is the high value, and XL is the low value

Hint: where SD is the standard deviation and N is the sample size

What is the margin of error, rounded to the nearest hundredth, for this experimental study?

Answer 1

Answer:

The correct answer is ME=+-6.54, I have taken this test.

Step-by-step explanation:

You have to use the formula that has been provided as a hint on the question. You need to substitute the given numbers into the first one to find the value of SD to then later use that value in the ME formula.

Answer 2

D) ME = ±1.30On this experimental study, we are given the following data:mean systolic blood pressure new drug of 121.7mean systolic pressure of leading is 123.1We deduct the two means.Thank you for your question. Please don't hesitate to ask in Brainly your queries.
