Suppose a basket of goods and services has been selected to calculate the cpi and 2014 has been selected as the base year. in 20
KATRIN_1 [288]
Consumer Price Index or also most commonly known as CPI is calculated through the equation,
                      CPI = (price at a certain year / price at base year) x 100
Since, we have chosen 2014 as the base year, the denominator of the fraction will be $86. Calculating the CPI for 2015,
                       CPI = ($90/$86) x 100
                              = <em>104.65</em>

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.

The Distributive Property also combines subtraction and multiplication. for example, . 3 * ( 5 - 2 ) = ( 3 * 5 ) - ( 3 * 2 ).
Sholpan [36]
So the problem ask to find or solve the problem using distributive property, so to calculate if using distributive property is just the same calculation if you are multiplying two number using a paper so the answer is 5(8)+5(90)+5(100), 40+ 450+500 = 990. I hope you understand my answer
