Answer:
Step-by-step explanation:
a. Given the mean is 28 and the standard deviation is 2.4
-Let X be the score of any random selection from the population.
-The probability that a randomly selected score is greater than 30.4:
Hence, the probability that the score is greater than 30.4 is 0.1587
b. The probability that a randomly selected score is less than 32.8 given mean =28 and the standard deviation is 2.4:
Hence, the probability that a random score is less than 32.8 is 0.9773
c. The probability that a random selection has a score of between 25.6 and 32.8.
-Given the mean=28 and sd=2.4, the probability is calculated as follows:
Hence, the probability that a random selection has a score between 25.6 and 32.8 is 0.8186
