what is the probability?
A jar contains 4 red marbles, numbered 1 to 4, and 12 blue marbles numbered 1 to 12.
a) A marble is chosen at random. If you’re told the marble is blue, what is the probability that it has the number 2 on it?
b) The first marble is replaced, and another marble is chosen at random. If you’re told the marble has the number 1 on it, what is the probability the marble is blue?

Unit 4: Discussion - Part 1
Question
Read the lecture for Chapter 4, and then answer the following:
Think of a brief example where you can use conditional
statements and write it in correct Java syntax. You may use
if-else-if statements or the switch statement. You may also use the
example you wrote in pseudo code for the discussion thread
2 during week 2 and convert it to Java, if you think it is
appropriate. Be mindful that we are not talking about
homework here. Do not post homework in this or any other discussion
thread. As always, show a screen capture of the
program running.
After writing your example, please explain if you think your
example could also be written in the other conditional statement
you did not chose. Explain why you think so, or why
not.

1. Design the logic for a program that outputs every multiple of
4, from 4 through 100
along with its value squared and cubed, e.g.,
The next number: 4
Squared: 16
Cubed: 64
The next number: 8
Squared: 64
Cubed: 512

Gasoline mileage (mpg) was measured on several cars of each of
four different makes (coded 1, 2, 3 and 4). The make of each car is
stored in the first column, and the mileage for each car is stored
in the second column, of Table A. You need to conduct an analysis
of variance to see if there are differences among the four makes in
gasoline mileage. You should also estimate the mileage of each of
the four makes of cars.
1. What is the value of the F‑statistic for testing the null
hypothesis that there are no differences in gasoline mileage among
the four makes of automobile?
2. What are the degrees of freedom associated with the numerator of
this test statistic?
3. What are the degrees of freedom associated with the denominator
of the F‑value for MAKE of car?
4. What is the estimate of the pooled variance within makes of cars
(i.e. the Error mean square)?
5. What are the degrees of freedom for this variance in #4?

Is there a statistically significant difference in mean scores between any of the following groups? Calculate and report the mean for each group. If one or more mean differences exist, please identify the groups with significantly different means. Use the most appropriate statistical test to answer this question at the alpha = 0.05 level of significance. Identify the hypothesis statements, test statistic, p-value, and your decision.
