I believe the answer is 4928 unless I did it wrong, but remember to upload the answer choices as well so other people trying to help can get a feel for what your options are just in case they are wrong.
To get this answer you <u>multiply 5 by .33</u> to see how much of the apples he gave and that would equal<u> 1.65</u> and then you <u>subtract 1.65 from 5 to get 3.35.</u>
<h2><u>
The answer is 3.35 and if you round that its is 3.</u></h2>
Answer:
B. Paired T Test
B. H0: μd = 0 and Ha: μd < 0 where μd= mean difference in blood pressure (calculated as aspirin - placebo)
Step-by-step explanation:
As the experiment is based on the difference between the results of a pair, the most appropiate test is a paired t-test.
If the 80 people group had been dividided in 2 and then compare the means for each group, it would have been a independent samples t-test.
For each pair, a variable d (for difference) is calculated and used as the outcome sample to perform the test.
Then, the null hypothesis will state that the population mean for this difference is not significantly different from 0, and the alternative hypothesis claiming it is signficant different from 0.
The sample means for the treatment group and the placebo is not individually calculated, as only the difference for each pair is used as sample in a paired t-test.
An equivalent fraction for 12/16 is 3/4 which is the simplest form but you another one would be 6/8
