In a study of parents who have children with attention deficit hyperactivity disorder (ADHD), 120 parents were asked to rate their overall stress level using the Parental Stress Scale (PSS). A higher score on the PSS scale indicates greater stress. The average stress level from the sampled parents was 52.98. The standard deviation of stress levels for the population of parents who have children with ADHD is known to be 10.34. Does the data provide convincing evidence that parents who have children with ADHD are extremely stressful? Note that a score on the PSS scale greater than 45 represents extreme stress. Conduct a hypothesis test at a 1% significance level. Make sure to check the required conditions and show all steps of hypothesis test properly (in the correct order as shown below).

(explanation please)

o Check the required conditions for a hypothesis test to determine if they are satisfied.

o Conduct a hypothesis test

- Describe the paramter ?? in words, and state the hyptheses using ??.

- Calcualte the test statistic and the p-value

- Determine whether we whouild reject the null OR fail to reject the null at 1% level

- Write an appropriate conclusion in the context of the problem.

A behavioral therapist records the number of children who are spanked and not spanked by their parents as a form of punishment in a sample of parents who were spanked by their parents as children. The following table shows the results of a chi-square goodness-for-fit test. If we expect to observe equal frequencies, then compute a chi-square goodness-of-fit test using a .05 level of significance and decide to retain or reject the null hypothesis. (This is the entire question as...
