I believe this is your answer. If any of the Y values share the same X values, then it’s not a function, but if it’s vice versa then it’s still a function. Hope this Helps!

suppose that the distribution for total amounts spent by students vacationing for a week in florida is normally distributed with
pentagon [3]

The probability that the SRS of 10 students will spend an average of between 600 and 700 dollars is 0.8132.

Let x be the total amount spent by students.

x follows normal distribution with mean μ = 650,

                                  standard deviation δ = 120

We take a simple random sample of size n = 10

We are asked to find average spending of 10 students ( x ) is between 600 and 700

We have to find P( 600 <= x <= 700)

According to the sampling distribution of the sample mean x, it follows an approximately normal distribution with mean μ{x} = μ and standard deviation  δ{x} = {δ}/{√n}

Therefore here mean of x,( μ{x} ) = 650 and

standard deviation of x, δ{x} = {120}/{√10} = 37.9473

The probability that the SRS of 10 students will spend an average of between 600 and 700 dollars is,

Let Z= x - μ / δ

Z₁ = 600 - 650 / 37.9473 = -1.32 similarly

Z₂ = 700 - 650 / 37.9473 = 1.32

From standard normal distribution table, P( -1.32 <  x  <  1.32) = 0.8132

The probability that the SRS of 10 students will spend an average of between 600 and 700 dollars is 0.8132
