A, B, and C. all of them are reasonable choices and wouldn’t give any conclusion, because not everyone has the flu
Answer: 0.0136
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
Sample size : 
The formula to calculate the z-score :-

For x = 24

The p-value = 
Hence, the probability that the sample mean age for 50 randomly selected women to marry is at most 24 years = 0.0136
Average rate= change in alt / change in time
r=-378/7=-54ft/min
