Elementary Statisties Page 4 B) Find a simple random using sample ofsze n=5 students, student and selecting every Sh student. Then compute the sample students. Use the systematic sampling by starting at the fifth mean and samp v Sample Standard Deviation. Score Squared Score C) Find the five number summary and construct a box-plot. Answer the following Questions. Show all your work. e that the heights of women are normally distributed with a mean of 63.6 inches and a standard en want to enlist in the U.S. Army, how many would you expect to meet the height )Assue2.5 inches. The U.S. Army requires that the heights of women be between 58 and 80 deviation cf inches. If200 wom requirements?

Explanation / Answer

SolutionD:

mean=63.6

Sd=2.5

need to find

P(58<X<80)

X~normal distribution

z=x-mean/sd

P((58-63.6)/2.5<Z<(80-63.6)/2.5))

P(-2.24<Z<6.56)

P(Z<6.56)-P(Z<-2.24)

pnorm(6.56)-(pnorm(-2.24)

0.9874545

ANSWER:

0.9874545*200=

197.4909

197 MEET THE REQUIREMENT
