Question 5

Can you answer all parts of this question with clearly showing which answer belongs to which part. Fill the chart with rounded to 2 decimal places 

The table provides the mean and standard deviation for two normal distributions. Two sample sizes are tested: 20 and 50 individuals. For each sample, calculate the probability that the mean is less than a specified value. Round answers to two decimals.

| Mean | Standard Deviation | Value | n=20: Pr(mean<value) | n=50: Pr(mean<value) |
|------|---------------------|-------|--------------------|--------------------|
| -5   | 5                   | -5.2  |                    |                    |
| 12   | 3                   | 12.5  |                    |                    |
