Assume that the weights (X) for a group of boys from 15 to 20 years follow the normal curve with a mean of 120 pounds and standard deviation of 5. The weight of a randomly chosen boy is 118 pounds. Compute the standard units of this weight. Standard unit equivalent of X is -0.2 Standard unit equivalent of X is 2 Standard unit equivalent of X is -0.4 Standard unit equivalent of X is 0.4

Is the following statement True (“T”) or False (“F”)?    Normal distribution is discrete rather than continuous. 

Is the following statement True (“T”) or False (“F”)?    When order doesn’t matter, it is Combination.

Let F(x) denotes the cumulative distribution (CDF) function of the random variable X that represents the number of EEG spikes in a randomly chosen 10-second EEG signal from an Epileptic patient. Given: P(X=0) = 0.20; P(X=1) = 0.50; P(X=2) = 0.20; P(X=3) = 0.10 Find F(1.5) F(1.5) = P(X=0) + P(X=1) + P(X=2) F(1.5) = P(X=0) + P(X=1) + P(X=2) + P(X=3) F(1.5) = P(X=1) + P(X=2) F(1.5) = P(X=0) + P(X=1)

The following table shows the probability that one diagnosed epileptic patient has seizures in one week. Based on previous research, the probability related to its occurrences are tabulated below: Find the subsets of the sample space for events S and M. Event M: (2, 3, 4) and Event S: (0, 1) Event M: (0, 1, 2) and Event S: (3, 4) Event M: (1, 2, 3) and Event S: (4) Event M: (0, 1) and Event S: (3, 4)

The following table shows the probability that one diagnosed epileptic patient has seizures in one week. Based on previous research, the probability related to its occurrences are tabulated below: Find the probabilities P(S) and P(M). P(S) = 82% and P(M) = 8% P(S) = 64% and P(M) = 36% P(S) = 18% and P(M) = 64% P(S) = 36% and P(M) = 64%

Is the following statement True (“T”) or False (“F”)?    If the sample is drawn from a nearly symmetric distribution, the normal approximation can be good even for a fairly small value of n. 

I hope you have a great spring break. Before you go, what is the due date of Pearson HW for Chapters 6,13, and 14?

Which of the following does the expectations theory not explain? 

According to the Federal Reserve Bank’s charter, the discount rate must always be [fedrate1] than the federal funds rate.
