The television show Cold Case has a 15 share, meaning that while it is being broadcast, 15% of the TV sets in use are tuned to Cold Case (based on the Nielson Media Research). A group that consists of 12 randomly selected households (each with one TV set) is taken. This is a binomial distribution.

For such a group of 12, determine the probability that exactly four TV sets are tuned into cold case.
For such a group of 12, determine the probability that 4 or more TV sets are tuned into Cold Case.
For such a group of 12, determine the probability that at most 4 TV sets are tuned into Cold Case.
For such a group of 12, determine the probability that no TV sets are tuned into Cold Case. Is this situation unusual? Why or why not?
Determine the mean and standard deviation.

Expert Solution

X is no of tv sets tuned into cold case follow binomial distribution with n =12,probability =0.15

A) P(x=4)=0.0688

B)P(X>=4)=0.0922

C) P( X<=4) = 0.9766

D) P(X=0) =0.1422

E) mean =1.8

Standard deviation =1.237

A recent broadcast of a television show had a 10 share, meaning that among 6000 monitored households with TV sets in use, 10% of them were tuned to this program. Use a 0.01 significance level to test the claim of an advertiser that among the households with TV sets in use, less than 15% were tuned into the program. Use the P-value method. Use the normal distribution as anapproximation of the binomial distribution A) Identify the null hypothesis, and alternative...

. The CBS television show 60 Minutes recently had a (market) share of 20, meaning that 20% of TV sets in use were tuned to 60 Minutes during its airing hour. An advertiser wants to conduct its own survey of 200 households using the 20% share value. Using the normal approximation to the binomial, with X=number of TV sets tuned to 60 Minutes at the appropriate hour, compute (a) P(X equal to or less than 35), (b) P(X is between...

The television show Law & Disorder has been successful for many years. That show recently had a share of 23, meaning that among the TV sets in use, 23% were tuned to Law & Disorder. Assume that an advertiser wants to verify that 23% share value by conducting its own survey, and a pilot survey begins with 13 households have TV sets in use at the time of a Law & Disorder broadcast. Find the probability that none of the...

The television show Green’s Anatomy has been successful for many years. That show recently had a share of 20, meaning that among the TV sets in use, 20% were tuned to Green’s Anatomy. Assume that an advertiser wants to verify that 20% share value by conducting its own survey, and a pilot survey begins with 12 households have TV sets in use at the time of a Green’s Anatomy broadcast. (Round answers to four decimal places) Find the probability that...
