Answer:
25
Step-by-step explanation:
We know that the standard error of the sampling distribution of sample means is
Standard error=standard deviation/√n
√n=standard deviation/Standard error
n=(standard deviation/Standard error)²
We are given that standard deviation=5 and standard error=1. So,
n=(5/1)²
n=5²
n=25.
Thus, the required sample size is 25.
Answer:
66mins
Step-by-step explanation:
6+6(-n+6)= 6 + (-6n) + 36
15 - 6 - 36 = (-6n -3n)
-27 = 9n
-3 = n
