Decreases increases flag this question question 7 1 pts the amount of time that it takes to complete a statistic exam has a skewed left distribution with a mean of 60 minutes and a standard deviation of 9 minutes. if 36 students are randomly sampled, determine the probability that the sample mean of the sampled students is less than 56 minutes. 0.3300 0.9962 0.6700 0.0038 flag this question question 8 1 pts t

0.0038

Step-by-step explanation:

Given : Mean :

Standard deviation :

Sample size = 36

The formula for z -score :

For x= 56 ,

The p-value =

Hence, the probability that the sample mean of the sampled students is less than 56 minutes  =0.0038.

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.
