1. Suppose that scores on a knowledge test are normally distributed with a mean of 71 and a standard deviation

of 6.

a. Label the curve: Show the mean and the value at each standard deviation:

b. If Angelica scored a 76 on the test, what is her z-score? (Draw her score on the curve above and label)

c. What percent of students did Angelica score higher than?

How can you tell?

d. If 185 students took the test, how many students scored higher than Angelica?

Step-by-step explanation:

X represent the random variable scores of knowledge test and is given as follows;

X-N (m= 71, s= 6)

A. For this question we can see the distribution in the file attached has a bell shaped graph and symmetrical around 71

B. To calculate the z score, we use the following method

z = (X-m)÷s

z = (76-71)÷6

z= 0.833

C. The probability of P( X> 76) using the standard normal distribution table is P(Z> 0.833) = 1 - P(Z<0.833) = 0.202

D. The number of students that scored more than Angelica is calculated as follows

n = 185×0.202

n= 154.16

154 to 155 students scored higher than Angelica.

step-by-step explanation:

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
