Answer 3

A certain naturopathic remedy being tested may be effective in increasing the life expectancy in people who have a rare disease. A control group consists of 25 subjects who have not taken the remedy and have a mean life expectancy of 72.1 years. A treatment group of the same size that has been given the remedy has a mean life expectancy of 79.5 years. After rerandomizing through simulation, the distribution plot for the differences of means was generated:

Answer 4

Using N = 50, what is the margin of error (ME), rounded to the nearest hundredth, and is the naturopathic remedy effective in increasing the life expectancy of people with this rare disease?

Answer 5

ME = ±2.87 and yes, the remedy is effective in increasing the life expectancy in people because the original difference of means of 7.4 years is beyond, statistically, what we would expect if the differences were random
ME = ±2.03 and yes, the remedy is effective in increasing the life expectancy in people because the original difference of means of 7.4 years is beyond, statistically, what we would expect if the differences were random
ME = ±8.11 and no, the remedy is not effective in increasing the life expectancy in people because the original difference of means of 7.4 years is within, statistically, what we would expect if the differences were random
ME = ±5.74 and no, the remedy is not effective in increasing the life expectancy in people because the original difference of means of 7.4 years is within, statistically, what we would expect if the differences were random

I agree

Answer 10

ok thank you. I have 3 more questions if you dont mind

Answer 11

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 133.7 millimeters of mercury. After rerandomizing the data 100 times, the following dot plot was generated.

Answer 12

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

ME = ±3.27
ME = ±9.81
ME = ±6.54
ME = ±6.20
