In a large school district, 16 of 85 randomly selected high school seniors play a varsity sport. in the same district, 19 of 67

Mashcka [7]

Answer:

Standard Error of the difference = 0.0695

Step-by-step explanation:

Its given that : In a large school district, 16 of 85 randomly selected high school seniors play a varsity sport

$\implies P_1=\frac{16}{85}\\\\n_1=85$

Also, in the same district, 19 of 67 randomly selected high school juniors play a varsity sport

$\implies P_1=\frac{19}{67}\\\\n_2=67$

Now, finding the standard error of the difference :

$\text{Standard Error = }\sqrt{\frac{P_1(1-P_1)}{n_1}+\frac{P_2(1-P_2)}{n_2}}\\\\\implies \text{Standard Error = }\sqrt{\frac{\frac{16}{85}(1-\frac{16}{85})}{85}+\frac{\frac{19}{67}(1-\frac{19}{67})}{67}}\\\\\implies\text{Standard Error = }0.0695$

Hence, Standard Error of the difference = 0.0695

The park charges 1.50 per ride.

1. Louisa bought 15 ride tickets at 1.50 each.

Equation: C = Entry Fee + 1.50t

t = 15.

c = 30.75

30.75 = Entry Fee + 1.50(15)

30.75 = Entry fee + 22.50

Entry fee = 30.75 - 22.50

Entry fee = $8.25

2. Entry fee was calculated as 8.25 from #1.

Tickets are 1.50 each.

He can spend 22.

22 = 8.25 + 1.50t

Subtract 8.25 from both sides:

13.75 = 1.50t

Divide both sides by 1.50:

t = 13.75 / 1.50

t = 9.2

He can buy 9 tickets.
