Answer: The probability that both televisions work is 0.5625 .
The probability at least one of the two televisions does not work is 0.4375.
Step-by-step explanation:
Given : Number of televisions received in shipment= 12
Number of defective televisions received in shipment= 3
Then proportion of defective televisions =
Using binomial probability formula, the probability of getting success in x trials is given by :-
If two televisions are randomly selected, then the probability that both televisions work will be :-
The probability at least one of the two televisions does not work will be :-

Answer: 11
Step-by-step explanation:
We know that the degree of freedom for a t-distribution is given by :-
, where n is the sample size.
Given : A repeated-measures experiment and a matched-subjects experiment each produce a t statistic with df = 10.
Then, the number of individuals participated in each study =
Hence, the number of individuals participated in each study =11.
