There is a significant difference between the proportion of male and the proportion of femaleemployees who are concerned with their physical wellness?Но:На:5. Is there a sufficient evidence to prove that the average shelf life of packed fruit juices is less than 5days?Но:На:6. A cooperative manager claims that the average daily income of the cooperative is P30,000 withstandard deviation of P2,000. To validate the claim, a cooperative member took a random sampleof 40 days and found out that the average daily income is P27,000. Assuming the distribution ofincome approximates the normal distribution, does the sample prove-ided evidence to support themanager's claim at 1% level of significance?Но:Ha:

35. A study reported in the Journal of Small Business Management 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 satis- faction. The sum of the ratings for the 18 items, ranging from 18-90, is used as the mea- sure of job satisfaction. Suppose that this approach was used to measure the job satisfaction for lawyers, physical therapists, cabinetmakers, and systems analysts. The results obtained for a sample of 10 individuals from each profession follow.
