Answer:
6
Step-by-step explanation:
You have a total of $30, but you can't spend it all on buckets of balls because first you have to pay the fee to attend the golf clinic.
So you have to figure out how much you have left after you spend $12 on fees.
$30−$12=$18
This means that you can spend $18 on buckets of golf balls.
At $3 each, how many buckets can you buy with $18?
18÷3=6
This means that you can buy
<u>6</u> buckets of golf balls at the clinic after paying the fee to join.
Equation:
12+3x=30
3x=18
x=6
There is not enough evidence to support the administrator’s claim and the true mean is not significantly greater than 280.
<h3>What is a statistical hypothesis?</h3>
A hypothesis to test the given parameters requires that we determine if the mean score of the eighth graders is more than 283, thus:
The null hypothesis:

The alternative hypothesis:

From the population deviation, the Z test for the true mean can be computed as:


Z = 0.756
Note that, since we are carrying out a right-tailed test, the p-value for the test statistics is expressed as follows:
P(z > 0.756)
P = 0.225
Since the P-value is greater than the significance level at α = 0.14, we can conclude that there is not enough evidence to support the administrator’s claim and the true mean is not significantly greater than 280.
