Answer:
(1,2)
Step-by-step explanation:
x value -2+4 /2 = 1
y value -2+6/2 = 2
Using the p-value method, the decision rule is:
- |z| < 1.645: do not reject the null hypothesis.
- |z| > 1.645: reject the null hypothesis.
<h3>What is the relation between the p-value and the test hypothesis?</h3>
Depends on if the p-value is less or more than the significance level:
- If it is more, the null hypothesis is not rejected.
- If it is less, it is rejected.
In this problem, we have a two-tailed test, as we are testing if the mean is different of a value. For a significance level of 0.1, the critical value of z(when a p-value of 0.1 is obtained) is of |z| = 1.645, hence the decision rule is:
- |z| < 1.645: do not reject the null hypothesis.
- |z| > 1.645: reject the null hypothesis.

Answer:
13/20
Step-by-step explanation:
Another way of asking this question is to ask for the difference of 1/4 and 9/10. The equation will start with 9/10 - 1/4.
9/10 - 1/4
Equations can only be added or subtracted when the denominators (bottom numbers) are the same. To do this, you must find a number that can be divided by both denominators. In this case, 20 can be divided by 4 and 10.
(9*2)/(10*2) = 18/20
(1*5)/(4*5) = 5/20
18/20 - 5/20 = 13/20
13/20 cannot be simplified as 13 is a prime number
