Question

Fernanda runs a large bowling league. She suspects that the league average score is greater than 150 per

Answer 1

Answer:

1.20

Step-by-step explanation:

Let mean be represented by M and standard deviation by d. The score will be x and sample number of games be n

To get the test statistic, t for Fernanda's test, we use the formula

$t=\frac {M-x}{\frac{s}{\sqrt n}}$

Substituting 156 for mean, M then 150 for score x and 30 for standard deviation while 36 for n then

$t=\frac {156-150}{\frac{30}{\sqrt 36}}$

t=1.20 when put in two decimal place
