Question

The boxplot of the exam scores for the students in an introductory statistics course is given below. The distribution of the scores is 30 40 50 60 70 Score 80 90 100 Symmetric and bell-shaped Positively skewed O negatively skewed Symmetric but not bell-shaped

Answer 1

#1) box plot

I If the longer part is to the left (or below) the median, the data is skewed left. hence above box plot is negatively skewed

# option b is correct

2)

Given:

here offer from university A =P(A)=0.6

and from university B =P(B)=0.5

probabilty of receiving offer from A, given received offer from B=P(A|B)=0.8

hence probability that both universities will make her an offer =P(A &B)

P(A &B)=P(A|B)*P(B)

   =0.8*0.5

=0.4

#hence probability that both universities will make her an offer =0.4

#option c is correct

Q3)

fromm above chart it is example of bar chart
