For each of the following situations, state whether the appropriate test would be a Independent Samples T test or Paired T Test,
Anvisha [2.4K]

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.

Sidana [21]

Answer:

Charlie could gather 30 pieces of fruits

Step-by-step explanation:

Given that : Charlie gathers apples pears and plums. The number of apples and plums are 10 partners, there are the same number of apples and pears.

Number of partners of apples and plums = 10

⇒ Number of apples = number of Plums = 10.

Also, number of apples and number of pears are same, therefore, number of pears = 10.

⇒ Total number of pieces of fruits = 10 + 10 + 10 = 30.

Therefore, Charlie could gather 30 pieces of fruits
