There is sufficient evidence to conclude that seeing the commercial improves the mean potential to purchase. A market research firm used a sample of individuals to rate the purchase potential of a particular product before and after the individuals saw a new television commercial about the product. The purchase potential ratings were based on a 0to 10 scale, with higher values indicating a higher purchase potential. The null hypothesis stated that the mean rating "after" would be less than or equal to the mean rating "before." Rejection of this hypothesis would show that thecommercial improved the mean purchase potential rating. Use a = 0.05 and the following data to test the hypothesis and comment on the value of the commercial.Purchase RatingIndividualAfterBefore16264377433698775866State the null and alternative hypotheses.

Directions: Write each claim as a mathematical statement (like above). Write the null and alternative hypothesis. Then determine and state whether the hypothesis test is left- tailed, right-tailed, or two-tailed. Sketch the curve and shade the appropriate area.

A study done in 1997 showed that 4.7% of mothers smoked cigarettes during their pregnancy. An obstetrician feels that this percentage is higher now. To test this, the obstetrician takes a sample of 150 mothers and finds that 9 of them smoked during their pregnancy. Test the obstetrician's claim at the a=0.05 level of significance.

A research study concluded that self-employed individuals do not experience higher job satisfaction than individuals who are not self-employed. In this study, job satisfaction is measured using 18 items, each of which is rated using a Likert-type scale with 1-5 response options ranging from strong agreement to strong disagreement. A higher score on this scale indicates a higher degree of job satisfaction. The sum of the ratings for the 18 items, ranging from 18-90, is used as the measure of job satisfaction. Suppose that this approach was used to measure the job satisfaction for lawyers, physical therapists, cabinetmakers, and systems analysts. Suppose the results obtained for a sample of 10 individuals from each profession follow.
