You measure 33 backpacks' weights, and find they have a mean weight of 36 ounces. Assume the population standard deviation is 12
.1 ounces. Based on this, what is the maximal margin of error associated with a 90% confidence interval for the true population mean backpack weight.
1 answer:
Answer:

Step-by-step explanation:
#Given a significance level of
and
the critical value is,
#the margin of error can then be calculated as:

Hence the margin of error is 3.4363
