Using appendix c-1 or appendix c-2 find the p-value for each test statistic. (round your answers to 4 decimal places.) test statistic p-value
(a) right-tailed test z = +2.82
(b) left-tailed test z = –1.28
(c) two-tailed test z = –1.55

a)

b)

c)

Step-by-step explanation:

It's important to refresh the p value method or p value approach . "This methos is about determining "likely" or "unlikely" by determining the probability assuming the null hypothesis were true of observing a more extreme test statistic in the direction of the alternative hypothesis than the one observed". Or in other words is just a method to have an statistical decision to fail to reject or reject the null hypothesis.

Part a

A right tailed test (usually called an upper test) is where the alternative hypothesis statement contains a greater than (>) symbol

The p value on this case is given by:

We can calculate the probability in excel like this:

"=1-NORM.DIST(2.82,0,1,TRUE)"

Part b

A left tailed test (usually called an lower test) is where the alternative hypothesis statement contains a greater than (<) symbol

The p value on this case is given by:

We can calculate the probability in excel like this:

"=NORM.DIST(-1.28,0,1,TRUE)"

Part c

A two tailed test (usually called an bilateral test) is where the alternative hypothesis statement contains a not equal symbol

The p value on this case is given by:

We can calculate the probability in excel like this:

"=2*NORM.DIST(-1.55,0,1,TRUE)"

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
