Answer:
And we can use the z score formula given by:
And if we find the parameters we got:
And we can find the z score for the value of 0.4 and we got:
And we can find this probability:
And if we use the normal standard table or excel we got:
Step-by-step explanation:
For this case we have the following info given:
represent the proportion of the company's orders come from first-time customers
represent the sample size
And we want to find the following probability:
And we can use the normal approximation since we have the following two conditions:
1) np = 158*0.26 = 41.08>10
2) n(1-p) = 158*(1-0.26) = 116.92>10
And for this case the distribution for the sample proportion is given by:
And we can use the z score formula given by:
And if we find the parameters we got:
And we can find the z score for the value of 0.4 and we got:
And we can find this probability:
And if we use the normal standard table or excel we got:
This is a more difficult one to explain. Let's start with the line to the right. It has a slope (m) of = -1 and a y-intercept of +3 (continue the line to see where it crosses the y-axis). So, the equation of that line is: y = -x + 3 when x ≥ 2. This can also be written as y = 3 - x when x ≥ 2. The only option that has that equation is A.
Answer: A
