2 + n = 7/8n - 15
2 + n - 7/8n = 7/8n - 7/8n - 15
2 + 1/8n = - 15
2 - 2 + 1/8n = - 15 - 2
1/8n = - 17
n = - 136
Answer: 
Step-by-step explanation:
Given : A market research worker interviewed a random sample of 18 people about their use of a certain product.
The results, in terms of Yes (Y) or No (N) are as follows:
Y-N-N-Y-Y-Y-N-Y-N-Y-Y-Y-N-Y-N-Y-Y-N.
The number of people said "Yes" for the product= 11
Then, the sample proportion for the users of the product =
We know that the sample proportion is the best estimate for the population proportion.
Thus the point estimate for population proportion : 
Answer:
y = 4.8
Step-by-step explanation:
y = k/x
4 = k/6
k = 24
y = 24/5
y = 4.8
For the first one I got X=5
and for the second one I got X=6
