The value of Q_{1} , Q_{2} ,, and Q_{3} of each data is shown in the diagram below

Group A

Mean = \frac{41+44+45+48+49+50+52+54+55+58}{10} =49.6
Median = 49.5
Range = 58-41=17
Interquartile Range = Q_{3}- Q_{1} =54.5-44.5=10

Group B
Mean = \frac{40+41+43+45+48+52+55+57+60+62}{10}=50.3
Median = 50
Range = 62-40=22
Interquartile range = 58.5-42 = 16.5

Correct statement: the time in Group B has a greater interquartile range

Describe how the graphs of square root and cube root functions are similar and how they are different.
Molodets [167]

Answer:

Just as the square root is a number that, when squared, gives the radicand, the cube root is a number that, when cubed, gives the radicand. Cubing a number is the same as taking it to the third power: 23 is 2 cubed, so the cube root of 23 is 2.

A researcher wants to investigate whether there is a relationship between annual company profit ($) and median annual salary pai
ahrayia [7]

Answer:

D. There is not convincing evidence of a relationship between annual company profit and median annual salary paid by the company.

Step-by-step explanation:

In this hypothesis test, the null hypothesis usually states that there is no relationship between the two variables in study.

In opposite, the claim that is being tested is the speculative hypothesis: that there is a significant relationship between both variables.

The researcher takes a sample and the P-value indicates the probability of getting that sample by pure chance <em>if the null hypothesis is true</em>.

Then, a very small P-value, below the significance level, indicates that the sample is very unusual if the null hypothesis is true, what gives evidence to reject the null hypothesis.

In this case, a P-value of 0.56 indicates that the sample is not unusual if the null hypothesis is true, so it gives no support to the claim that the null hypothesis is false and that there exists a relationship between the two variables in study.
