zimovet [89]

Answer:

Option D) $275

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = $235

Standard Deviation, σ = $20

We are given that the distribution of amount of money spent by students is a bell shaped distribution that is a normal distribution.

Formula:

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

We have to find the value of x such that the probability is 0.975

P( X < x) = P( z < \displaystyle\frac{x - 235}{20})=0.975  

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

P( z < 1.960) = 0.975

\displaystyle\frac{x - 235}{20} = 1.960\\x =274.2 \approx 275

Approximately 97.5% of the students spent below $275 on textbook.
