Question

Suppose Jason read an article stating that in a 2003-2004 survey, the average American adult man aged 19-30 drank an
average of 1.47 liters of plain water per day with a standard deviation of 0.09 liters. Jason wants to find out if the men at his
college drink a similar amount per day. He asks 45 of his male classmates in his Introductory Biology class to record the
amount of water they drink in one day, and he is willing to assume that the standard deviation at his college is the same as in
the 2003-2004 survey.
Jason wants to construct a 99% confidence interval for μ, the average amount of water the men at his college drink per day.
Have the requirements for constructing a z-confidence interval for a mean been met?
Mark all
of the following requirements that have been met with yes, and all the requirements that have not been met with no.
☐☐ ☐ ☐
The sample is a simple random sample.
The population standard deviation is known.
The population from which the data are obtained is normally distributed, or the sample size is
large enough.
The requirements for constructing a z-confidence interval for a mean have been met.
Answer Bank
yes
no

Expert Solution

Step 1

Here the given information is

Suppose Jason read an article stating that in a 2003-2004 survey, the average American adult man aged 19-30 drank an average of 1.47 liters of plain water per day with a standard deviation of 0.09 liters. Jason wants to find out if the men at his college drink a similar amount per day. He asks 45 of his male classmates in his Introductory Biology class to record the amount of water they drink in one day, and he is willing to assume that the standard deviation at his college is the same as in the 2003-2004 survey.

I.e,

Population standard deviation = 0.09

Sample size = 45
