## my statlab statistics distribution questions

A radio station claims that the amount of advertising per hour of broadcast time has an average of 14
minutes and a standard deviation equal to 1.6 minutes. You listen to the radio station for 1​ hour, at a randomly selected​ time, and carefully observe that the amount of advertising time is equal to 16 minutes. Calculate the​ z-score for this amount of advertising time. Round your answer to two decimal places as needed.

How to solve the statistics Question

## Suppose that Yuki is selecting her schedule for next semester

Suppose that Yuki is selecting her schedule for next semester and has identified four English​ courses, three art​ courses, three psychology​ courses, and four history courses as possibilities to take. Assume that no two of the courses are offered at conflicting times.
​(a) Can the fundamental counting principle be used in solving this​ problem? Explain.
​(b) If any of the courses are offered at conflicting​ times, can you still use the fundamental counting​ principle? Explain.

Hint:_
Notepad:-
The fundamental counting principle states that if a series of tasks is being performed and the first task can be done in a​ ways, the second can be done in b​ ways, the third can be done in c​ ways, and so​ on, then all the tasks can be done in a times
b times c times ...ways.

This question can be answered by our tutors later, or someone can volunteer to provide a solution.

## Example of a probability question in Pearson MyStatLab

Probability Question Example
The following question is a probability question for tossing a fair coin presented in Pearson My STATLAB statistics. Note that probability concepts are the building blocks for any introductory statistics course. To solve the problem, one would have to write down the possible outcomes, and associate each outcome with some probabilities.
Two fair coins are tossed​ (say a dime and a​ quarter). The two possible outcomes for a single coin are​ heads, h, and​ tails, t. Give each of the following.
​(a) the sample space
​(b) the probability of heads on the dime
​(c) the probability of heads on the quarter
​(d) the probability of getting both heads
​(e) the probability of getting the same outcome on both coins
