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 30 workers at a large department store had a mean of 4.8. The standard deviation of the population is 1.4. Is there enough evidence to support the researcher's claim at 0L= 0.05? Assume that the variable is normally distributed. Use the critical value method with tables. State the hypotheses and identify the claim with the correct hypothesis. HOE] Hl :E] onetailed two-tailed This hypothesis test is a Find the critical value(s). Round the answer to at least two decimal places. If there is more than one critical value, separate them with commas. Critical value(s): E] Part 3 of 5 Compute the test value. Always round z score values to at least two decimal places. Z = X\fPart 5 of 5 Summarize the results. There is (Choose one) that the average number of sick days is less than 5. enough evidence to reject the claim not enough evidence to support the claim enough evidence to support the claim not enough evidence to reject the claim
