Suppose that prices of Fuji apples are normally distributed. Ryan selected a simple random sample of 14 grocery stores and found that the mean price of Fuji apples at these stores was $1.84 per pound and that the standard deviation was $0.14 per pound. Ryan plans to use this information to construct a confidence interval for ?, the mean price of a pound of Fuji apples. Have the requirements for a one-sample t?confidence interval been met?
The requirements (have/have not) been met based on these reason
a. the sample is not random.
b. the sample is random.
c. the population standard deviation is known.
d. the population is normal.
e. the sample size is too small.
f. the population is not normal.
g. the population standard deviation is not known.
h. the sample size is large enough.

The lengths of nails produced in a factory are normally distributed with a mean of 4.91 centimeters and a standard deviation of 0.05 centimeters. find the two lengths that separate the top 4% and the bottom 4%. these lengths could serve as limits used to identify which nails should be rejected. round your answer to the nearest hundredth, if necessary.
