A study conducted by the Center for Disease Control that asked 15,000 students about their sleep habits showed that about 73% of high school students did not get the required 8 hours of sleep per night. Let p be the proportion of high school students who do not get 8 hours of sleep daily. 1.What is the mean of the sampling distribution of p?

2. Find the standard deviation of the sampling distribution of p. Round to 4 decimal places. ( decimal form pls obvi )

3. Find the probability of selecting a sample of 15,000 students in which between 70% and 75% of the students did not get 8 hours of sleep every day.

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

the answer is y = 11.54

hope this : )
