How many standard deviations is the sample proportion trom the mean of the distribution of sample proportions? (Round to the nearest tenth as needed) b. What is the probablity that a second sample selected would have a proportion less than 0 432 (Round to tour deanal places as needed ) Enter your answer in each of the answer boxesExplanation / Answer
a) here std deviation =0.05
therefore number of std deviation from mean =(X-mean)/std deviaiton =(0.43-0.46)/0.05=-0.6 ~ 0.6 (absolute value)
b) for probability =P(Z<-0.6)=0.2743
