A deck of cards contains RED cards numbered 1,2,3,4,5,6 , BLUE cards numbered 1,2,3,4 , and GREEN cards numbered 1,2 . If a single card is picked at random, what is the probability that the card is NOT GREEN?

Diastolic blood pressures are approximately normally distributed with a mean of 75 and a standard deviation of 10.

a.What is the 90th percentile of diastolic blood pressure?

b.If we consider samples of 20 patients, what is the 90th percentile of the mean diastolic blood pressure?

In a survey of

210

males ages 20 to?24,

38?%

were neither in school nor working. In a survey of

220

females ages 20 to?24,

45?%

were neither in school nor working. These samples are random and independent. At

?=0.06?,

can you support the claim that the proportion of males ages 20 to 24 who were neither in school nor working is less than the proportion of females ages 20 to 24 who were neither in school nor?working? Complete parts?(a) through?(e) below.

?(a) Identify the claim and state

Organize the student's heights in a frequency table of 5 classes with suitable class width (class

interval). (You have to construct a table with classes, frequency, cumulative frequency, relative

frequency, and percent relative frequency).
