Why do two normal distributions that have equal standard deviations have the same shape?

You can still ask an expert for help

Step 1

In this case, we need to explain the reason for the two normal distribution with equal standard deviation have same shape.

Step 2

The normal distributions were bell shaped or symmetric about the population mean and the standard deviation states the square root of deviations about the mean. That is, spread from the mean. Thus, two normal distribution with equal standard deviation have same shape.

The manager of the store in the preceding exercise calculated the residual for each point in the scatterplot and made a dotplot of the residuals.

The distribution of residuals is roughly Normal with a mean of $0 and standard deviation of $22.92.

The middle 95% of residuals should be between which two values? Use this information to give an interval of plausible values for the weekly sales revenue if 5 linear feet are allocated to the stores

Find the expected count and the contribution to the chi-square statistic for the (Group 1, Yes) cell in the two-way table below.

$\begin{array}{|cccc|}\hline & \text{Yes}& \text{No}& \text{Total}\\ \text{Group 1}& 710& 277& 987\\ \text{Group 2}& 1175& 323& 1498\\ \text{}\text{Total}& 1885& 600& 2485\\ \hline\end{array}$

Round your answer for the excepted count to one decimal place, and your answer for the contribution to the chi-square statistic to three decimal places.

Expected count=?

contribution to the chi-square statistic=?
