QUESTION 5

The table below contains data about the returns to capital (in percentage points, %) of a random sample of 9 South African companies. Suppose that the returns to capital of South African companies is normally distributed.

Using the data provided in the table, the value of the test statistic that must be used to test the hypothesis that the mean returns to capital is at least 10, rounded off to 3 decimal places is . Testing at the 5% level of significance, the critical value of this hypothesis, rounded off to 3 decimal places is . Use a YES for reject H0 and NO for do not reject H0. In the space provided and writing your answer in capital letters, do you reject or do not reject the null hypothesis H0? . (Note: write your final answers to 3 decimal places and when writing your answer use "." (3.250) instead of "," (3,250) with no spaces between digits).

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
