Answer:

a. We get 56 heads out of 100 tosses.
We will use one sample proportion test
x = 56
n = 100



Formula of test statistic =
=
=
refer the z table for p value
p value = 0.8849

p value of part B is less than Part A because part B have 10 times the number the tosses.
B is the answer to the question
Answer:
It is 2 bags.
Step-by-step explanation:
You have to divide 3/4 and 3/8. The 3/4 goes first.
Possibly $16.89 because you multiply 55.08 and .08 to find 4.41 then you subtract that to 55.08 to find the total cost without tax which is 50.67. Then you divide by 3 because there are 3 girls to 16.89.
