I’m most sure that the answer is A.
First, we get the standard error of the mean using
σm = σ / √N
= 5 / √100
= 0.5
Next, we subtract and add 1.96 standard deviations from the mean (since the confidence interval is 95%). So,
8 ±1.96 (0.5)
= 8 <span>± 0.98
The answer is

It CORRECT
Answer: Unlikely
Step-by-step explanation:
Given: The probability of choosing a penny from the 1980s from the bag of pennies without looking=
We know that the probability of any event lies between 0 and 1.
- If probability of occurring event is 0 then the event is impossible.
- If probability of occurring any event is 1 then the event certain.
- If probability of occurring any event lies between 0.5 and 1 then the event is said to be likely.
- If probability of occurring any event lies between 0 and 0.5 then the event is said to be unlikely.
Since, 0.075 lieas between 0 and 0.5, therefore the event is said to be unlikely.
