4 7/8 = 4 14/16 = 78/16
2 7/16 = 39/16
39/16 + 39/16 + 39/16 + 39/16 = 156/16
78/16 + 78/16 = 156/16
156/16 + 156/16 = 312/16 = 19 8/16 = 19 1/2

Answer: 19 1/2 inches

While preparing for a party a party planner began with 75 pieces of candy she ate 5 pieces while she was working then she put eq

Sloan [31]

The easiest way to find this answer is to work through it step by step.

She starts with 75 pieces.

She eats 5 pieces, so the # of pieces goes down from 75 to 75-5 = 70.

So she has 70 pieces left to put in the bags.

She puts the same amount in each of 10 bags... so we divide 70 by 10 to find the # of pieces in each bag.

70 divided by 10 is 7.

She put 7 pieces in each bag.

For a left-tailed test, the critical value of z so that a hypothesis test would reject the null hypothesis at 1% significance le

mars1129 [50]

Answer:

C.-2.33

Step-by-step explanation:

We are given that

Significance level, $\alpha =1$ %=0.01

We have to find the critical value of z for a left-tailed test.

To find the critical value , we will use the z-table at significance level 0.01 for left-tailed test.

By using the z-table at significance level 0.01 for left-tailed test

The critical value of z at 1% significance level for left-tailed test

=-2.33

We get p-value by using z-critical value

P-value=0.0099<0.01

So, hypothesis test would be reject the null hypothesis at at 1% significance level.

Hence, the critical value of z=-2.33

Option C is true.
