If the calculated test statistic is 2.148 when the critical value is 2.348, should you reject or not reject the null hypothesis,
Lisa [10]
The approach of critical value is used to determine likely or unlikely through determination whether observed test statistics is more than it would have been if null hypothesis was true. In other words, test statistics is compared to critical value and decision made.
If test statistics is more than critical value, the null hypothesis is rejected. Otherwise, null hypothesis is not rejected.

In the current scenario, test statistics (2.148) is less than critical value (2.348) and thus null hypothesis is not rejected.

5. A pair of jeans costing
Levart [38]
So $39.50 is the price when you are paying full price, which can be represented by 100%. If you’re paying 25% less, than you are only paying 75% of the original price. Simply multiply $39.50 by 75%(expresses as 0.75) to determine the sale price. 39.50(.75)=29.62 The closest value to that is $29.50, so D is the answer.
