Answer #1

Here we need degrees of freedom to find the test statistic value from the p-value.

Suppose degrees of freedom = df = 17

Let's use minitab:

Click on Graph >>> Probability Distribution Plot >>>Select 4th image>>>OK

So we get the following Image in which put the given information.

Then click on Shaded Area

look the following image:

Then click on OK so we get the following output

From the above output the test statistic value is either 25.71, or 9.588

Use your degrees of freedom and try to find test statistic value for the given p-value = 0.16.

The P-value for a chi-square test is always one-tailed. This is true because of all of the following reasons, EXCEPT: Group of answer choices Observed data that is either higher or lower than the null hypothesis predicts will result in a positive chi-square value. Only a large positive value of chi-square provides stronger evidence to conclude HA. A chi-square distribution is skewed. The chi-square statistic is always positive, unlike a z or t statistic which can be ether positive or...
