A study shows that 20% of college students pray daily in their own religious beliefs. In a group of 300 college students, find t
svetlana [45]

Answer:

0.2805

Step-by-step explanation:

Given that p = 20% = 0.2, n = 300.

The mean (μ) = np = 0.2 * 300 = 60

The standard deviation (σ) = \sqrt{np(1-p)}=\sqrt{300*0.2(1-0.2)}=6.93

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

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

For x = 57:

z=\frac{57-60}{6.93 } =-0.43

For x = 62:

z=\frac{62-60}{6.93 } =0.29

From the normal distribution table, P(57 < x < 62) = P(-0.43 < z < 0.29) = P(z < 0.29) - P(z < -0.43) = 0.6141 - 0.3336 = 0.2805
