Answer:

A, the first option

Step-by-step explanation:

1. Add 15 to both sides to cancel out the 15 from the left. (5x < -50)

2. Divide both sides by 5 to cancel out the 5 from the left. ( x < -10)

This inequality does not include the -10 because it's less than -10 not less than or equal to. So, the point at -10 should not be filled in.

x has to be LESS than, so the graph should include numbers that are less than -10 which leads us to our answer, A.

In the book Business Research Methods, Donald R. Cooper and C. William Emory (1995) discuss a manager who wishes to compare the

S_A_V [24]

Answer:

Null hypothesis is: U1 - U2 ≤ 0

Alternative hypothesis is U1 - U2 > 0

Step-by-step explanation:

The question involves a comparison of the two types of training given to the salespeople. The requirement is to set up the hypothesis that type A training leads to higher mean weakly sales compared to type B training.

Let U1 = mean sales by type A trainees

Let U2 = mean sales by type B trainees

Therefore, the null hypothesis (H0) is: U1 - U2 ≤ 0

This implies that type A training does not result in higher mean weekly sales than type B training.

The alternative hypothesis (H1) is: U1 - U2 > 0

This implies that type A training indeed results in higher mean weekly sales than type B training.

If the correlation coefficient is .87, is its relationship considered to be strong positive,weak positive,strong negative,weak n

myrzilka [38]

Answer:

strong positive correlation co efficient

Step-by-step explanation:

correlation:-

A correlation co-efficient is a numerical measure of some type of correlation,meaning a statistical relationship between two variables.

positive correlation:-

Positive correlation occurs when an increase in one variable increases the value in another.

Negative correlation:-

negative correlation occurs when an increase in one variable decreases the value of another.

Strong positive correlation:-

A co-efficient of correlation of + 0.87 indicates a strong positive correlation between the independent variables

Strong negative correlation:-

A co-efficient of correlation of - 0.87 indicates a strong negative correlation between the independent variables.

Zero correlation:-

There is no relationship is called zero correlation

weak positive correlation:-

A co-efficient of correlation below 0.2 indicates a weak positive correlation between the independent variables.

weak negative correlation:-

A co-efficient of correlation below -0.2 indicates a weak negative correlation between the independent variables.
