Answer:
7/22
Step-by-step explanation:
From the question given above, the following data were:
Drama n(D) = 25
Sport n(S) = 140
Both drama and sport n(DnS) = 60
Not in drama or sport n(DnS)ᶜ = 105
Total or sample space n(S) = 330
Probability of not in drama or sport P(DnS)ᶜ =?
The probability that the student chosen is not in drama or sport can be obtained as follow:
P(DnS)ᶜ = n(DnS)ᶜ / nS
P(DnS)ᶜ = 105 / 330
Express the above to its lowest terms
P(DnS)ᶜ = 7/22
Therefore, the probability that the student chosen is not in drama or sport is 7/22

Answer:
The appropriate null hypothesis is 
The appropriate alternative hypothesis is 
Step-by-step explanation:
The average car had a fuel economy of 22.6 MPG. Test if the current average is less than this.
At the null hypothesis, we test if the current average is still of 22.6 MPG, that is:

At the alternative hypothesis, we test if the current mean has decreased, that is, if it is less than 22.6 MPG. So

Step-by-step explanation:
1. Multiply 18.5 by 6.
18.5 x 6 = 111
2. Subtract 129.25 by 111.
129.25 - 111 = 18.25
Therefore, the answer is A. 18.25
