In one region of the country, the household credit card debts are approximately normally distributed with a mean of $16,125 and a standard deviation of $7,875. Find the amount of debt corresponding to 32nd percentile of size-81 means of household credit card debts.

$12424

Step-by-step explanation:

Given that:

Mean (μ) = $16,125, Standard deviation (σ) = $7,875.

The z score corresponding to the 32nd percentile from the normal distribution table is -0.47. That means that the z score of -0.47 = 0.32 = 32nd percentile.

The z score is given by the equation:

, where x is the raw score

Substituting the values and calculating for x:

x ≈ 12424

The debt corresponding to the 32nd percentile is $12424

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
