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 1 of 5 State the hypotheses and identify the claim. Ho: (Choose one) O
