Pediatricians work an average of 48 h per week. The standard deviation is 12 hours. What percentage of pediatricians work more t
cricket20 [7]

Answer: 2.28 %

Step-by-step explanation:

Given : Mean : \mu=\ 48

Standard deviation :\sigma= 12

The formula to calculate the z-score :-

z=\dfrac{x-\mu}{\sigma}

For x = 72

z=\dfrac{72-48}{12}=2

The p-value = P(2

1-0.9772498=0.0227502\approx0.0228

In percent, 0.0228\times100=2.28\%

Hence, the  percentage of pediatricians work more than 72 h per​ week = 2.28 %

a student must have an average on five test that is greater than it equal to 80% but less than 90% to receive a final grade of B
Bad White [126]

Answer:

  89–100

Step-by-step explanation:

Let x represent the grade on the fifth test. The average for 5 tests wants to be between 80 and 90, so we have ...

  80 ≤ (78 +62 +91 +80 +x)/5 ≤ 90

Multiplying by 5 gives

  400 ≤ 311 +x ≤ 450

Subtracting 311 gives the range for the fifth test grade.

  89 ≤ x ≤ 139

Since the maximum available score is 100, the range on the 5th test for an overall B grade is ...

  89 ≤ x ≤ 100 . . . . where x is the grade on the 5th test
