Given

total sample = 65

number of successes = 19

margin of error = +-2.8%

Find

point estimate

lower and upper limits.

Step-by-step explanation

point estimate = number of successes/total sample

so , point estimates =


(19)/(65)=0.292

b) lower limit = 65 - (2.8% of 19)= 65-0.532 = 64.468

upper limit = 65 +(2.8% of 19) = 65 +0.532 = 65.532

Final Answer

a) 0.292

b) lower limit =64.468 , upper limit = 65.532

interval (64.468 ,65.532)
