answer: Subtract sixteen from both sides of the equation
2 +16 -16=22x -16
x = 4/5
Answer:
e. The probability of observing a sample mean of 5.11 or less, or of 5.29 or more, is 0.018 if the true mean is 5.2.
Step-by-step explanation:
We have a two-tailed one sample t-test.
The null hypothesis claims that the pH is not significantly different from 5.2.
The alternative hypothesis is that the mean pH is significantly different from 5.2.
The sample mean pH is 5.11, with a sample size of n=50.
The P-value of the test is 0.018.
This P-value corresponds to the probability of observing a sample mean of 5.11 or less, given that the population is defined by the null hypothesis (mean=5.2).
As this test is two-tailed, it also includes the probability of the other tail. That is the probability of observing a sample with mean 5.29 or more (0.09 or more from the population mean).
Then, we can say that, if the true mean is 5.2, there is a probability P=0.018 of observing a sample of size n=50 with a sample mean with a difference bigger than 0.09 from the population mean of the null hypothesis (5.11 or less or 5.29 or more).
The right answer is e.
It already is a decimal unless you mean a repeating decimal, it would be .26 with a line over the number.
Answer:
(7-5)
Step-by-step explanation:
According to PEMDAS, parenthesis go first. But there are two sets of parenthesis so the one inside the other goes first.
Next would be [3+(2*2)]
Then, [3+4]
Then, -8/1
Then, -3(7)
So the question would be 4-8-21
Which gives you -25 as an answer.
I realize that you weren't asking for the whole thing but maybe there are follow up questions.
Answer:
he earns $15 an hour. the equation is 12h=t
Step-by-step explanation:
you can make the equation 180=12x where x equals the amount per hour
divide 12 by both sides and you get x=15 which means he makes 15 dollars an hour
