Answer #1

H0: Null Hypothesis: The views of a group on a policy on gun control.are the same.

HA: Alternative Hypothesis: The views of a group on a policy on gun control.are different.

the Chi-square value. is not as follows:

Observed (O) Expected (E) (O - E)2/E
35 20 11.25
10 20 5.00
15 20 1.25
Total = = 17.5

So,

the Chi-square value. is 17.5

    2. Goodness-of-fit tests Normal population Aa Aa Manufacturing processes, such as coin minting, are subject to small variations due to variations in materials, temperature, and humidity. The variations in materials, temperature, and humidity from their norms are just as likely to be positive as negative but are more likely to be small than large. Consider the 1 coin issued by Belgium. Realizing that there are small variations in the minting process and random error in the weighing process, it might...
