Answer:
False
Step-by-step explanation:
given that a race car driver tested his car for time from 0 to 60 mph, and in 20 tests obtained an average of 4.85 seconds with a standard deviation of 1.47 seconds.
Sample size n = 20
since population standard deviation is not known, we can use t critical value for finding out the confidence interval
df=19
t critical = 2.045
Margin of error = 
conidence interval = Mean±Margin of error
= 
The given confidence interval is (4.52, 5.18)
Hence the statement is false.
B. 700
1000 out of 700 is the same as 10 out of 7 but simplified
Answer:
B)
