Explanation / Answer

AS PER chegg policies i am answer Q1 only,

Q1)

(I) Fuel economy (miles per gallon) of used car - NUMERIC

(II) Number of auto insurance claims in a month - NUMERIC

hence, option 3) (I) Numeric , and (II) Numeric is correct

Q2)

(I) Number of auto insurance claims in a month - numeric (histogram, stem and leaf plot)

(II) Local name for soft drinks (e.g. Soda, Pop, Coke, etc) - categorial (pie chart, bar graph)

hence option 4) (I) Stem-and-leaf display , and (II) Bar graph is correct

Q3)

(I) Type of automobile (e.g. compact, sedan, SUV) - nominal scale of measurement

(II) Duration (in minutes) of flight between two locations - ratio scale of measurement

hence option 2) (I) Nominal , and (II) Ratio is correct

Q4)

since middle line in box plot is towards left, distribution is skewd to right

1) Right-skewed

Q5)

since middle line of box plot is neither towards left nor towards right, distribution is normal.

2) Symmetric

Q6)

tail towards right, hence distribution is skewed to right

1) Right-skewed
