Answer: $5,605
Step-by-step explanation:
Monthly earning = 1200
Commission = 7.5% on sales over 4000
Current month sales = 21400
Total monthly earning :
$4000 + commission on sales over 4000
Total earning for the current month:
$4000 + commission on sales
Commission on current month's sales:
7.5% of 21400
0.075 × $21,400
= $1605
Total amount earned :
$4000 + $1605 = $5,605

Answer:
There is not enough evidence to conclude that the mean pH level is 8.5.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 8.5
Sample mean, = 8.42
Sample size, n = 49
Alpha, α = 0.05
Sample standard deviation, s = 0.16
First, we design the null and the alternate hypothesis
We use two-tailed t test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since, the test statistic does not lies in the acceptance region, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.
There is not enough evidence to conclude that the mean pH level is 8.5.
