solution:-.
given that n = 180 (number of students)
p = 0.5 (probability of correct identification)
standard deviation = sqrt[p(1-p)/200] =
sqrt[(0.5)(0.5)/180]
= 0.0373
(a)p(0.5 < x < 0.6) = p[(0.5 - 0.5) / 0.0373 < Z <
(0.6 - 0.5) / 0.0373]
= p(0 < z < 2.6810)
= p(z < 2.6810) - p(z < 0)
= 0.9963 - 0.5
= 0.4963

You plan to conduct a marketing experiment in which students are to taste one of two different brands of soft drink. Their task is to correctly identify the brand tasted. You select a random sample of 200 students and assume that the students have no ability to distinguish between the two brands. (Hint: If an individual has no ability to distinguish between the two soft drinks, then the two brands are equally likely to be selected.) What is the probability that the sample will have between 55% and 61%...
