You take a random sample of 25 student athletes and measure their diastolic blood pressure. the sample mean is 70 (the units are mm hg) and the population variance = ď 2 (this will change in the parts of the question below). consider the null hypothesis that diastolic blood pressure is over 80mm hg versus the relevant alternative hypothesis (ha : ⵠ≤ 80). compute the p-value for each part below and state if you would reject the null at the î± = 4% level: a) ď 2 = 225 b) ď 2 = 900 4.1 using the information from # 4 a)â’b) above, calculate the p-value if the null hypothesis was that diastolic blood pressure equals 80mm hg versus the relevant alternative hypothesis (what is in each case, tell if you would you reject the null hypothesis at the î± = 4% level. a) b)

hope this ! have a great day.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
