Answer:
7.79771≤x≤8.20229
Step-by-step explanation:
Given the following
sample size n = 8
standard deviation s = 0.238
Sample mean = 2.275
z-score at 980% = 1.282
Confidence Interval = x ± z×s/√n
Confidence Interval = 8 ± 1.282×0.238/1.5083)
Confidence Interval = 8 ± (1.282×0.15779)
Confidence Interval = 8 ±0.20229
CI = {8-0.20229, 8+0.20229}
CI = {7.79771, 8.20229}
Hence the required confidence interval is 7.79771≤x≤8.20229

Answer:
B.The mean weight of dogs at Lawrenceville’s Veterinarian Office is about 72 pounds and the mean weight of dogs at Snellville’s Veterinarian Office is about 73 pounds.
Step-by-step explanation:
Lawrenceville’s Veterinarian Office distribution is almost symmetrical so the mean is almost the same as the median
Snellville’s Veterinarian Office distribution is left skewed so mean is less than the median, mean is less than 76
