The byu testing center is known for being the location with the most prayers said per capita. researchers asked a random sample of 49 byu students in winter 2019 to estimate the number of prayers they said in the byu testing center the previous semester. researchers plan to use these data to estimate the mean number of prayers said by students the previous semester in the byu testing center with 99% confidence. they obtained a sample mean of 10.92 prayers with a standard deviation of 7.53. what is the confidence interval estimate? '

Step-by-step explanation:

Given : Sample size : n= 49, it means its a large sample.

Significance level :

Critical value :

Sample mean:

Standard deviation:

The confidence interval for population mean is given by :-

Hence, the 99% confidence interval for population mean=  

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
