Answer:
a)0.154<p<0.48[
b)n≅ 6.57
c)n=2401
Step-by-step explanation:
n = 60
Sample proportion = p = 16/60 = 0.266
a) Find a 95% two-sided confidence interval on the true proportion of helmets
90 % confidence interval fro population is
hence population proportion lies in the confidence interval
b) helmets must be tested to be 95% confident
point of estimates i s- 0.266
Margin of error = 0.02
after putting values we get
n = 6.56
n≅ 6.57
c)large must the sample be
The sample is calculted as
n=2401
