Answer: a) The probability is approximately = 0.5793
b) The probability is approximately=0.8810
Step-by-step explanation:
Given : Mean :
Standard deviation :
a) The formula for z -score :
Sample size = 1
For x= 63 in. ,
The p-value =
Thus, the probability is approximately = 0.5793
b) Sample size = 35
For x= 63 ,
The p-value =
Thus , the probability is approximately=0.8810.
To make this a little clearer, let's give the pairs of inequalities the same denominator:
