Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

The image contains a problem regarding the statistical analysis of newborn girls' weights, with reference to normal and t distributions. The details are as follows:

Summary Statistics:
- Sample size ($ n $) = 169
- Sample mean ($ \bar{x} $) = 33.2 hg
- Sample standard deviation ($ s $) = 7.9 hg
- Confidence level = 90%

The task is to select the correct statistical distribution and fill in the answer box as necessary.

Options for the selection:
- **A**: $ t_{\alpha/2} = $ [Round to two decimal places as needed.]
- **B**: $ z_{\alpha/2} = $ [Round to two decimal places as needed.]
- **C**: Neither the normal distribution nor the t distribution applies.

The indicated choice is option **C**.

Additionally, there is a prompt stating "Click to select and enter your answer(s)."
