Suppose that the financial stress, a type of stress related to the perception of not having the necessary to satisfy basic needs, in a general population is normally distributed with a mean of 52 and a standard deviation of 8 (M= 52, SD= 8) (in a scale of 0-100). Our friend works at a restaurant that has been serving at limited capacity during the last 6 months due the COVID pandemic, he scored a mean of 68 in the financial stress measure.

  1. Suppose that the financial stress, a type of stress related to the perception of not having the necessary to satisfy basic needs, in a general population is normally distributed with a mean of 52 and a standard deviation of 8 (M= 52, SD= 8) (in a scale of 0-100). Our friend works at a restaurant that has been serving at limited capacity during the last 6 months due the COVID pandemic, he scored a mean of 68 in the financial stress measure. Is this score sufficiently above the mean for us to assume that his score in financial stress is different compared to the general population?

Step 1. State your hypotheses.

H0:

H1:

Step 2. Set the significance level. = .05

Step 3. Do the statistics.

a. Compute the z score.

b. Determine whether the value of the test statistic is in the critical region (hint: draw a diagram)

Step 4. Draw conclusions. (Would you reject the null hypothesis?)
