Personal best finishing times for a particular race in high school track meets are normally distributed with mean 24.6 seconds a
Dovator [93]

Answer: the qualifying time in seconds is about 25.3

Step-by-step explanation:

Since the personal best finishing times for a particular race in high school track meets are normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = personal best finishing times for a particular race.

µ = mean finishing time

σ = standard deviation

From the information given,

µ = 24.6 seconds

σ = 0.64 seconds

The probability value for the top 15% of finishing time for runners to qualify would be (1 - 15/100) = (1 - 0.15) = 0.85

Looking at the normal distribution table, the z score corresponding to the probability value is 1.04

Therefore,

1.04 = (x - 24.6)/0.64

Cross multiplying by 0.64, it becomes

1.04 × 0.64 = x - 24.6

0.6656 = x - 24.6

x = 0.6656 + 24.6

x = 25.3 seconds
