In a survey of 474 U. S. women, 365 said that the media has a negative effect on women's health because they set unattainable standards for appearances. Let rho denote the proportion of all women who think media has a negative impact on women's health because they set unattainable standards for appearance. Find a point estimate for rho and also construct a 95% confidence interval for

point estimate=p=0.77

95 % confidence interval= [0.732,0.808]

Step-by-step explanation:

Let p be the point estimate of rho. The point estimate can be computed as

p=x/n

p=365/474

p=0.77.

The 95% confidence interval for rho can be computed as

where,

p=0.77

q=1-p=1-0.77=0.23

(rounded to three decimal places).

50- 250 is correct i did that one too

step-by-step explanation:

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
