Question

+ 6 The giren values are discrete. Use the the region of the normal distribution probability. The probability of continuity that at least correction and describe corresponds to the indicated 44 boys

Answer 1

Ans: In order to calculate the probability of atleast 44 boys by appliyng normal approximation to the binomia distribution, we arr not provided the values of n and p. Therefore, it cannot be calculated with the given information

However i will solve question 5

In order to apply norma approximation to the binomail distribution, the following two conditions should be met

(i) np >= 5

i.e. 20* 0.9 = 18 which is greater than 5. The first condition is met

(ii) n(1-p) >= 5

i.e 20*(1-0.9) = 2 which is not greater than 5. therefore, the second condition is not met

Hence, we cannot apply normal approximation to this binomial distribution
