Answer: 
Step-by-step explanation:
The confidence interval for population mean is given by :-
, where 
is the sample proportion, n is the sample size , 
is the critical z-value.
Given : Significance level : 
Sample size : n= 85
Critical value : 
Sample proportion: 
Now, the 99% confidence level will be :
Hence, the 99% confidence interval estimate of the true proportion of families who own at least one DVD player is

Answer:
5/8 - 5/12 = (5×3/8×3)-(5×2/12×2)15-10/24 = 5/24
Step-by-step explanation:
first find out the LCM ( Lowest Common Multiple ) of the denominators ( here:24 ) and multiply the denominator and numerator , both with the required no. to make the denominator as equal as the LCM [( 5×3/8×3 ) - ( 5×2/12×2)] and subtract / add the numerators. the answer you get is the correct answer.
hope that is helpful for your future.
best of luck
