State whether each situation has independent or paired (dependent) samples. a. A researcher wants to compare the hand–eye coord
ination of men and women. She finds a random sample of 100 men and 100 women, and measures their hand–eye coordination. b. A researcher wants to know whether professors with tenure have fewer office hours than professors without tenure. She observes the number of office hours for professors with and without
a. A researcher wants to compare the hand–eye coordination of men and women. She finds a random sample of 100 men and 100 women, and measures their hand–eye coordination = paired samples
b. A researcher wants to know whether professors with tenure have fewer office hours than professors without tenure. She observes the number of office hours for professors with and without tenure. = independent samples
Explanation:
Paired-samples t tests compare scores on two different variables but for the same group of cases; independent-samples t tests compare scores on the same variable but for two different groups of cases.
Because the account PAYS compound interest per year it's called depreciation. So you do 100-3.4 = 96.6, the divide by 100 = 0.966 Then you do 0.966^3 x £6000 = £5408.6
