You measure 32 turtles' weights, and find they have a mean weight of 73 ounces. Assume the population standard deviation is 7.9 ounces. Based on this, what is the maximal margin of error associated with a 95% confidence interval for the true population mean turtle weight. Give your answer as a decimal, to two places

Answer:
Margin of error = 2.74 ounces
Step-by-step explanation:
We are given the following in the question:
Sample mean,
= 73 ounces
Sample size, n = 32
Alpha, α = 0.05
Population standard deviation, σ = 7.9 ounces
Margin of error:
Putting the values, we get,
Thus, the maximum margin of error associated with a 95% confidence interval for the true population mean turtle weight is 2.74 ounces
