Sick Days in Bed A researcher wishes to see if the average number of sick days a worker takes per year is less than 5. A random sample of 29 workers at a large department store had a mean of 4.7. The standard deviation of the population is 1.3. Is there enough evidence to support the researcher's claim at a = 0.10? Assume that the variable is normally distributed. Use the P-value method with tables. Part: 0/5 Part 1 of 5 State the hypotheses and identify the claim. Ho: (Choose one) ▼ H: (Choose one) ▼ This hypothesis test is a (Choose one) ▼ test. Part: 1/5 Part 2 of 5 Compute the test value. Always round z score values to at least two decimal places.
