53.35/11 = 4.85 for 1 key chain
4.85 *4 = 19.40
1.60 mi +1.75 mi = 3.35 mi = 3 7/20 mi
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.
