The correct answer for the question that is being presented above is this one: "B. There is no association between gender and party affiliation." At the α = .10 level, the correct conclusion for the test is that B. There is no association between gender and party affiliation. 

The distribution of salaries of professional basketball players is skewed to the right. Which measure of central tendency would be the best measure to determine the location of the center of the distribution? A) mode
B) mean
C) frequency
D).median Frequency distributions that are skewed to the right, what is the relationship of the mean and median?

Answers

Answer:

Median

mean>median

Step-by-step explanation:

When the data is skewed to right the suitable average is median. Median is suitable because it is less effected by extreme values and thus locate the center of the distribution perfectly. Here the salaries of basket players are skewed to right and the best measure of central tendency to measure the center of distribution is median.

When the frequency distribution is rightly skewed then the relationship of mean and median is that mean is greater than median that is Mean>median.

Hence when the distribution is skewed to right the best choice to measure the center of distribution is median and when the data is skewed to right mean is greater than median.

1. There are 25 students who started computer programming in elementary school and 25 students who started computer programming in middle school. The first group had a mean final project grade of 95% and the second group had a mean final project grade of 92%. The line plot shows the differences after 10 rerandomizations. Determine whether the difference in the means of the two groups is significant based on the line plot. Explain your answer.

Answers

the answer is attached below

Answer:

the difference  in the means is not significant

Step-by-step explanation:

Let’s begin first by finding the difference between the means of the 2 groups.

Difference in means = 95% - 92% = 3%  Now  let’s look at  the line plot of the 10 rerandomizations.   On that plot, 4 of the randomizations have a difference of 3.  

Probability of having a difference of 3 = 4 / 10 *100%  = 40%  

So just by mixing up the scores from both classes and finding the difference between the mean of 2 randomly defined groups, there was a difference of 3 between the 2 means in 40%  of the trials.

Since this probability is so large, the difference in the means is not significant.  The line plot shows that it would be very likely that the difference in the means is just due to random chance

2x+2y find the slope and y intercept

Answers

Equations can be graphed.
Expressions can't.
(2x + 2y) is not an equation.
It can't be graphed.
It has no slope, and no intercept.
It's just an expression that stands for a number.
We can't find the number until we know the values of 'x' and 'y'.

If you told us a number that's equal to (2x + 2y), THEN we'd have
an equation, which could be graphed, and it would have a slope
and an intercept.

The current winning teams final score is 52.08 ft. miguel's teammates threw 12.26 ft, 12.82 ft, 13.75 ft. what does miguel need to score to tie?

Answers

Winning tem score = 52.08

Miguel teammates, = 12.26+12.82+13.75+x

Here, x= score of Miguel need to tie,

It would be, 52.08 = 12.26+12.82+13.75

 x = 52.08 - 38.83 = 13.25

So, 13.25 ft is your answer
