In a sample of 593 new websites registered on the internet, 28 were anonymous (i. e., they shielded their name and contact information).

(a) construct a 95 percent confidence interval for the proportion of all new websites that were anonymous. (round your answers to 4 decimal places.)
(b) may normality of p be assumed?

a)

b)Yes

Step-by-step explanation:

n = 593

x = 28

Confidence level = 95%

So, at 95% = 1.96

Formula of confidence interval of one sample proportion:

=

=

=

Hence a 95 percent confidence interval for the proportion of all new websites that were anonymous is

b)  May normality of p be assumed?

Condition for normality : np>10 and np(1-p)>10.

and

27.871  and 26.561063

Hence p is assumed to be normal since the condition is satisfied

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
