Question

wants to verify that 10% share value by co ducting its own suroy and a pilot survey begins with 10 households having TV sets in use at the time of a Lindsay and Tobias broadcast (Round to three decimal places as needed.) b. Find the probability that at least one household is tuned to Lindsay and Tobias to three decimal places as needed.) c. Find the probability that at most one household is tuned to Lindsay and Tobias. (Round to three decimal places as needed.) d. If at most one household is tuned to Lindsay and Tobias, does it appear that the 10% share value is wrong? why or why not? e to MyStatLab!

Explanation / Answer

Solution:-

a. P(x=0) = (0.90)^10 = 0.349

b. P(X >= 1) = 1 - P(x=0) = 1 - 0.349 = 0.651

c. P(x ? 1) = P(x=0 or x=1) = 0.349 + 0.387 = 0.736

d. option A.

Formula : Binomial distribution = nCr*p^r*q^(n-r)
