WebbThe mean of the distribution is equal to 200*0.4 = 80, and the variance is equal to 200*0.4*0.6 = 48. The standard deviation is the square root of the variance, 6.93. The probability that more than half of the voters in the sample support candidate A is equal to the probability that X is greater than 100, which is equal to 1- P(X< 100). Webb30 aug. 2024 · Suppose we would like to find the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1. Then we will subtract the smaller value from the larger value: 0.8413 – 0.6554 = 0.1859. Thus, the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1 is approximately 0.1859. WebbIts the same thing because the <= statement refers to less than or equal to so V not <= 5 means V is not less than or equal to 5 and must be greater than 5.
