Answer: 30.5
Step-by-step explanation:
16, 5, 25, 6, 36, 7, 49, 8, 64, 9, 81, 10, 100
The pattern is starting at 1 then squaring it. Then, you move to the next number after one, then square it, and so on.
Step-by-step explanation:
a. The point estimate is the mean, 47 days.
b. The margin of error is the critical value times the standard error.
At 31 degrees of freedom and 98% confidence, t = 2.453.
The margin of error is therefore:
MoE = 2.453 × 10.2 / √32
MoE = 4.42
c. The confidence interval is:
CI = 47 ± 4.42
CI = (42.58, 51.42)
d. We can conclude with 98% confidence that the true mean is between 42.58 days and 51.42 days.
e. We can reduce the margin of error by either increasing the sample size, or using a lower confidence level.
