Given the discrete uniform population 32 f(x) = x = 2, 4, 6, 10, elsewhere, find the probability that a random sample of size 54, selected with replacement, will yield a sample mean greater than 4.1 but less than 4.4. Assume the means are measured to the nearest tenth.
8.4.20 Given the discrete uniform population shown to the right find the probability that a random sample of size 96, selected with replacement, will yield a sample mean greater than 9.2 but less than 9.9. Assume the means are measured to the nearest tenth. x 1, 9, 17 f(x)= 3 0, elsewhere Click here to view page 1 of the standard normal distribution table Click here to view page 2 of the standard normal distribution table The probability is (Round...
Given the discrete uniform population with parameter N = 8, find the probability that a random sample of size 36, selected with replacement, will produce a sample mean greater than 5. Answer using 4 decimals.
Given the discrete uniform population with parameter N = 8, find the probability that a random sample of size 36, selected with replacement, will produce a sample mean greater than 5. Write the answer with 4 decimals.
Suppose that the random variable X has the discrete uniform distribution f(x) = { 1/4, r= 5, 6, 7, 8. 0, otherwise. A random sample of n = 45 is selected from this distribution. Find the probability that the sample mean is greater than 6.7. Round your answer to two decimal places (e.g. 98.76). P= the absolute tolerance is +/-0.01
Assume that the probability mass function of X is given by P(X = 1) = P(X = 2) = P(X = 3) = 1/3 A random sample of n = 36 is selected from this population. Find the probability that the sample mean is greater than 2.1 but less than 2.5, assuming that the sample mean would be measured to the nearest tenth.
The population s1700. A random sample of 25 managers is selected from this population. Find the probability that the mean annual salary of the sample is less than $55,000 mean annual salary for managers is $59,100, with a standard deviation of The population s1700. A random sample of 25 managers is selected from this population. Find the probability that the mean annual salary of the sample is less than $55,000 mean annual salary for managers is $59,100, with a standard...
n 0.05, find the probability that the sample Let X be a continuous random variable that follows a distribution skewed to the left with ? = 87 and ? = 22, Assuming mean, E, for a random sample of 69 taken from this population will be a. less than 82.0 Round your answer to four decimal places. P(less than82.0) b. greater than 89.5 Round your answer to four decimal places. P(greater than 89.5) -
A random sample of size n1 = 16 is selected from a normal population with a mean of 75 and variance of 288. A second random sample of size n2 = 9 is taken independently from another normal population with mean 80 and variance of 162. Let X^1 and X^2 be the two-sample means. Find the probability that X^1 + X^2 is less than 158. Select one: a. 0.7385 b. 0.3085 c. 0.6915 d. 0.4235
