Answer:
option (B) 912 ± 42.6
Explanation:
Data provided in the question:
Standard deviation = 64 square feet
Sample size, n = 15
Mean = 912
Confidence level = 99%
Now,
Confidence interval = Mean ± z[s ÷ √n]
here,
z = 2.58 for 99% confidence level
Thus,
Confidence interval = 912 ± 2.58[64 ÷ √15]
or
Confidence interval = 912 ± 2.58[64 ÷ √15]
or
Confidence interval = 912 ± [ 2.58 × 16.525 ]
or
Confidence interval = 912 ± 42.63
= 912 ± 42.6
Hence,
The answer is option (B) 912 ± 42.6
