A repeated-measures study and an independent-measures study both produce a t statistic with df = 20. The repeated-measures study used more subjects than the independent-measures study.
A. True
B. False

B. False

Step-by-step explanation:

We have that both studies have the same production for what the first part of the statement mentions.

"A repeated-measures study and an independent-measures study both produces a t statistic with df = 20"

And they ask us if it is false or true, if one produces more than the other.

Starting from the first statement, the second statement is false because they produce the same, therefore they will be the same subjects.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
