Answer:
Accept the null hypothesis if it is two tailed test.
Step-by-step explanation:
The null hypotheses can only be accepted if it is a two tailed test and calculated chi square must be less than the critical value of chi square.
Then the difference between the the observed and expected frequencies will be zero.
where
H0 : σ²-σ²= 0 Ha: σ²-σ²≠0
For this the critical region would be greater than the calculated value of chi square. If so we will accept the null hypothesis and reject the alternative hypothesis.
Based on the information given regarding the equation, it can be noted that Tania doesn't have enough money.
<h3>How to solve an equation</h3>
Your information is incomplete. Therefore, an overview will be given. Let's assume that the price of a jawbreaker is 0.45.
Therefore, the cost of 21 jawbreakers will be:
= 21 × 0.45
= 9.45
In this case, the person has 8.32. Therefore, it can be noted that she doesn't have enough money.

Basically f(x)=5x means whatever number you plug in will be your x coordinate, and the result will be your y coordinate.
(1,5) (2,10) (3,15) (4,20) and so on. 1,2,3 and 4 are x coordinates plugged into the equation, the y coordinate is whatever 1,2,3 and 4 multiplied by 5 is.
Answer: a. Ratio b. Nominal c. Interval d. Ordinal
Step-by-step explanation:
1)Ratio:You can do all sort of arithmetic on the cholesterol level.
2)Nominal: These cannot be ordered or arithmetic cannot be applied
3)Interval: It is interval because it is a number and midnight means 0 so you cannot use it for division
4)Ordinal: You can arrange it in increasing or decreasing order.
