Suppose a marketing company wants to determine the current proportion of customers who click on ads on their smartphones. It was
andrezito [222]

Answer:

The 92% confidence interval for the true proportion of customers who click on ads on their smartphones is (0.3336, 0.5064).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

For this problem, we have that:

n = 100, p = 0.42

92% confidence level

So \alpha = 0.08, z is the value of Z that has a pvalue of 1 - \frac{0.08}{2} = 0.96, so Z = 1.75.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.42 - 1.75\sqrt{\frac{0.42*0.58}{100}} = 0.3336

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.42 - 1.75\sqrt{\frac{0.42*0.58}{100}} = 0.5064

The 92% confidence interval for the true proportion of customers who click on ads on their smartphones is (0.3336, 0.5064).

Answer the picture below.
pav-90 [236]

Answer:

The distance between point M and point L is 8

Step-by-step explanation:

The given points on the coordinate are M = (- 2, 4) and L = (4, - 1)

The formula for determining the distance between two points is expressed as

d = √(x2 - x1)^2 + (y2 - y1)^2

Where

y2 = final value of y = - 1

y1 = initial value of y = 4

x2 = final value of x = 4

x1 = initial value of x = - 2

Therefore,

d = √(4 - - 2)^2 + (- 1 - 4)^2

d = √6^2 + (-5)^2

d = √36 + 25

d = √61 = 8
