Suppose you administered an anxiety test to a large sample of people and obtained normally distributed scores with a mean of 45 and standard deviation of 4
There are 200 students in a sample. How many of these students will have scores that fall under the score of 41?

This can be calculated using the z-score formula. The z-score for 41 would be (41-45)/4= -0.75. According to the standard normal distribution table, a z-score of -0.75 falls within the range of 0.216 to 0.1938 of the study population. Therefore, about 40.76 or 41 students out of the 200 will have scores that fall under 41.
