Assume that it takes a college student an average of 10 minutes to find a parking spot in the main parking lot. Assume also that

rjkz [21]

Answer:

75% of college students exceed 6.63 minutes when trying to find a parking spot.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 10 minutes

Standard Deviation, σ = 5 minutes

We are given that the distribution of time for parking is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(X < x) = 0.25

We have to find the value of x such that the probability is 0.25.

P(X < x)

$P( X < x) = P( z < \displaystyle\frac{x - 10}{5})=0.25$

Calculation the value from standard normal z table, we have,

$P(z$

$\displaystyle\frac{x - 10}{5} = -0.674\\x = 6.63$

Hence, 75% of college students exceed 6.63 minutes when trying to find a parking spot.

27/20

= 20/20 + 7/20

= 1 + 7/20

= 1.00 + 0.35

= 1.35

List of values to remember (extras):

0.05 = 1/20 = 5%
0.10 = 1/10 = 10%
0.15 = 3/20 = 15%
0.20 = 1/5 = 20%
0.25 = 1/4 = 25%
0.30 = 3/10 = 30%
0.35 = 7/20 = 35%
0.40 = 2/5 = 40%
0.45 = 9/20 = 45%
0.50 = 1/2 = 50%
0.55 = 11/20 = 55%
0.60 = 3/5 = 60%
0.65 = 13/20 = 65%
0.70 = 7/10 = 70%
0.75 = 3/4 = 75%
0.80 = 4/5 = 80%
0.85 = 17/20 = 85%
0.90 = 9/10 = 90%
0.95 = 19/20 = 95%
1.00 = 1 = 100%
