Answer:

The p-value is 0.0229

Step-by-step explanation:

With H_{a}: p > 0.47 we have an upper-tail alternative. Because the p-value is defined as the probability of getting a value at least as extreme as the value observed. The observed value is given by the test statistic z = 1.997 which comes from a standard normal distribution. Therefore, we compute the p-value in the following way P(Z > 1.997) = 0.0229, i.e., the p-value is 0.0229

4. The length of a rectangle is 4 more than its width. The perimeter of the rectangle is 60cm.
sergey [27]

Step-by-step explanation:

let width = w

if width = w, then length = w + 4

Therefore the perimeter is 2w + 2(w+4)

2w + 2(w+4) = 4w + 8

perimeter = 60cm

4w + 8 = 60

<em>-8</em>

4w       = 52

<em>divide each side by 4</em>

w = 13

length = w+4

therefore, length = 17
