Answer 1

1)

a)The weight of a T bone steak can any value such as 45 grams or 100 grams etc. Thus it a continuous random variable.

b) Number of hits in a day to a website can only take values such as 1,2,3......... . so, it is a discrete random variable.

c) The political party affiliation of adults in united states does not have any possible numerical outcomes.So, it is not a random variable.

d)The amount of rain in city B during april can take on any non-negative value on the real number line, such as 10.35 inches or 32.8 inches, and therefore is continuous rather than discrete.

e) The exact time it takes to evaluate 27+72 can take on any non-negative value on the real number line, such as 10 sec or 3.67 sec, and therefore is continuous rather than discrete.

f) The number of people with Blood type A in a random sample of 48 people can take only positive integer values, such as 0, 1,2,3.......or 48 and thus is a discrete random variable.
