male 6
female 8
female 8
male 3
female 7
female 5

a. There is no difference between the two groups.
b. Females on average received 6 tickets while males received 5, because the data is discrete.
c. 56% of the female students received more than 6.3 tickets.
d. Gender is significant.

c. 56% of the female students received more than 6.3 tickets.

Step-by-step explanation:

Null hypothesis is the statement against which alternative hypothesis is formed and then their validity is checked to conclude whether to accept or reject the null hypothesis.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
