Answer:
The 99% confidence interval for the mean number of toys purchased each year is between 7.6 toys and 7.8 toys.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 7.7 - 0.1 = 7.6 toys
The upper end of the interval is the sample mean added to M. So it is 7.7 + 0.1 = 7.8 toys
The 99% confidence interval for the mean number of toys purchased each year is between 7.6 toys and 7.8 toys.
