Question

2. You believe that the mean number of cats present in Guney Campus Manzara at any given moment is 4. Please answer each part below seper- ately. a. You have counted the number of cats 9 times, and $ \bar{X} $ turned out to be 3.3. If a frequent visiter of the place told you that $\sigma^2$ for the number of cats is 0.7, what would be your final decision if you want your CIs to include the true population parameter 95 times out of 100 times? b. You have counted the number of cats 9 times, and $ \bar{X} $ turned out to be 5. If $S_X^2 = 1.1$, what would be your final decision if you are willing to have a confidence level of 96%?

Manzara at any given moment is 4. Please answer each part below seper-
ately.
a. You have counted the number of cats 9 times, and X̅ turned out to be
3.3. If a frequent visiter of the place told you that σ^2 for the number of cats
is 0.7, what would be your final decision if you want your CIs to include the
true population parameter 95 times out of 100 times?
