In a​ survey, 36​% of the respondents stated that they talk to their pets on the telephone. A veterinarian believed this result
Damm [24]

Answer: p value is 0.1685.

Step-by-step explanation:

Since we have given that

The survey is conducted on a random sample of 240 pet owners.

Out of them, number of owners spoke to their pet on telephone = 79

n = 240

x = 79

\hat{p}=\dfrac{x}{n}=\dfrac{79}{240}=0.33

Our hypothesis would be

H_0:p=0.5\\\\H_1:p>0.5

Formula for test statistic would be

\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}\\\\=\dfrac{0.33-0.36}{\sqrt{\dfrac{0.36(1-0.36)}{240}}}\\\\=-0.96

p value = 0.1685

Hence, p value is 0.1685.

nasty-shy [4]

Answer:

132cm ^ 2

Step-by-step explanation:

then solve the bottom rectangle, 8x7 = 56cm

then solve the triangle, we know the entire bottom is 19cm, and 7 is subtracted, thereforth leavin 12, since there is 2 triangles its a base of 6, with a height of 8 making 48cm (and since there is 2 triangles no need to divide by 2)

28+56+48 = 132cm^2
