The height measurements of ten-year-old children are approximately normally distributed with a mean of 54.1 inches, and standard deviation of 2.7 inches. a) what is the probability that a randomly chosen child has a height of less than 51.85 inches?

The probability that a randomly chosen child has a height of less than 51.85 inches is 0.2033

Step-by-step explanation:

Mean = 54.1 inches

Standard deviation = 2.7 inches

We are supposed to find the probability that a randomly chosen child has a height of less than 51.85 inches

P(x<51.85)

Formula :

Substitute the values in the formula :

Refer the z table for p value

p value = 0.2033

Hence the probability that a randomly chosen child has a height of less than 51.85 inches is 0.2033

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450
