Question

100%

59% of all statistics classes require a statistical calculator and 28% require the use of a computer that has statistical software. Of the classes that require a statistical calculator, 19% also require the use of a computer. If a statistics course is selected at random find: (round to 4 decimal places where possible)

a. P(Statistical Calculator) =

b. P(Statistical Software) =

c. P(Require a Statistical Calculator and Statistical Software) =

d. P(Require a Statistical Calculator GIVEN Require Statistical Software) =

Expert Solution

Step 1

Define the events,

A : requires statistical calculator

B: requires statistical software

It is given ,

P(A) = 59% = 0.59

P(B) = 28% = 0.28

P(B|A) = 19% = 0.19

So, P(A∩B) = P(B|A) * P(A) = 0.1121

The population of interest for both people can be defined as, “People who shop at the Johnson City, NY Wegmans store”. Here is what each person did to collect their sample: Lexie: She stood outside at the entrance to the store on 3 different days and times and surveyed every 15th person to walk by her. She surveyed 10 people each time to get her 30. Jennifer: She went to Wegmans after her nursing shift first thing Wednesday morning to buy deodorant since she ran out. When she was in the pharmacy area she surveyed all the people around her and then, to get up to 30 surveys, she went to the health food section and surveyed everyone she was there.
