Answer:

Refer to the figure attached.

Detailed explanation:

Here are several pointers for relating the histogram to the mean and median.

1) In cases where the histogram shows a right skew, the mean exceeds the median.

2) When the histogram nearly resembles a symmetrical shape, the mean and median will be relatively similar.

3) In situations where the histogram is skewed to the left, the mean will fall below the median.

Thus, based on the provided data, the median is 29.5, and the mean approximates this value.

Consequently, it indicates that the histogram is nearly symmetric.

Therefore, the data set that probably has a mean closest to 29.5 is represented in the accompanying figure.

Mookie Betts of the Boston Red Sox had the highest batting average for the 2018 Major League Baseball season. His average was 0.

Answer:

Binomial probability, with $n = 5, p = 0.352$

Step-by-step explanation:

Each time Mookie Betts stepped up to bat, there were only two possible results: either he achieved a base hit or he didn't. The odds of hitting during each at-bat remain unaffected by prior attempts. Therefore, the binomial probability distribution applies to tackle this problem.

Binomial probability distribution

The chance of getting exactly x successes over n trials, considering p probability.

His batting average stood at 0.352.

This indicates that $p = 0.352$

Let's assume he bats five times in tonight's matchup against the Yankees.

This means that $n = 5$

Leona [12618]

Answer:

a) Slope: $\hat \beta_1 =\frac{7625.9}{1248.9}=6.106$

Intercept: $\hat \beta_o = 157.955 -6.106 (69.686)=-267.548$

b) $r=\frac{7625.9}{\sqrt{[1248.9][94228.8]}}=0.657$

Additionally, the coefficient of determination is $r^2 = 0.657^2 =0.432$

Step-by-step explanation:

Definitions and data provided

The correlation coefficient is a measure that quantifies the strength of the relationship between two variable movements, denoted as r and ranging between -1 and 1.

The sum of squares refers to the total of the squared deviations, where deviation is defined as the difference between each value and the grand mean.

When performing multiple regression, the aim is to analyze the relationship between multiple independent variables and one dependent variable.

n=110, $\sum x_i y_i = \sum (X-\bar X)(Y-\bar Y) =7625.9,\sum x^2_i=\sum (x-\bar x)^2 =1248.9, sum y^2_i=\sum(y-\bar y)^2 =94228.8$
