A study of class attendance and grades among first-year students at a state university showed that, in general, students who missed a higher percent of their classes earned lower grades. Class attendance explained 16% of the variation in grade index among the students. What is the numerical value of the correlation between percent of classes attended and grade index

Answers

Answer:

the numerical value of the correlation between percent of classes attended and grade index is r = 0.4

Step-by-step explanation:

Given the data in the question;

we know that;

the coefficient of determination is r²

while the correlation coefficient is defined as r = √(r²)

The coefficient of determination tells us the percentage of the variation in y by the corresponding variation in x.

Now, given that class attendance explained 16% of the variation in grade index among the students.

so

coefficient of determination is r² = 16%

The correlation coefficient between percent of classes attended and grade index will be;

r = √(r²)

r = √( 16% )

r = √( 0.16 )

r = 0.4  

Therefore,  the numerical value of the correlation between percent of classes attended and grade index is r = 0.4

Make a conditional relative frequency table for the columns of movie type. Determine which statement has the strongest association.


Do you prefer watching a comedy, a drama, or a thriller movie?
Comedy Drama Thriller Row Totals
Males 35 12 75 122
Females 46 65 18 129
Column Totals 81 77 93 251
Males prefer comedy movies.
Females prefer drama movies.
Males prefer thriller movies.
Females prefer thriller movies.

Answers

The statement which has the strongest association is Males prefer thriller movies.

To obtain which statement has the strongest association, we calculate the probability of each given statement and select that which has the highest probability value.

• probability of  Males prefer comedy movies :

n(males who prefer comedy) / n(males)

= 35 / 122 = 0.287

• probability of Females prefer drama movies :

n(Females who prefer drama) / n(females )

= 65 / 129 = 0.504

• probability of Males prefer thriller movies.

n(males who prefer prefer thriller ) / n(males)

= 75 / 122 = 0.615

• probability of Females prefer thriller movies.

n(females who prefer prefer thriller ) / n(females)

= 18 / 129 = 0.140

Comparing the probabilities obtained, Males prefer thriller has the highest probability, thus the strongest association.

Answer:

x=45°

Step-by-step explanation:

The 160° plus the unlabeled angle to the left of it are supplementary, meaning when added they equal 180°. The unlabeled angle will therefore be 20°. The angle across from the 20° will also be 20°. 115° + 20° = 135°. Now all that is left on the top half is x.

180° - 135° = 45°
