Your father earned​ $34,000 per year in 1984. To the nearest​ dollar, what is that equivalent to in 2014 if the CPI in 2014 is 2
xeze [42]

Answer:

The answer is : 70288.46

Step-by-step explanation:

Your father earned​ $34,000 per year in 1984.

The CPI in 2014 is 215 and the CPI in 1984 is​ 104.

The CPI or consumer price index examines the weighted average of prices of goods and services like transportation, food etc.

The Current income equivalent will be = value in 1984 X ( CPI in 2014/CPI in 1984)

34000\times\frac{215}{104} = 70288.46

A professor would like to test the hypothesis that the average number of minutes that a student needs to complete a statistics e
professor190 [17]

Answer:

\chi^2 =\frac{15-1}{25} 16 =8.96

The degrees of freedom are given by:

df = n-1 = 15-1=14

The p value for this case would be given by:

p_v =P(\chi^2

Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true deviation is not ignificantly lower than 5 minutes

Step-by-step explanation:

Information given

n=15 represent the sample size

\alpha=0.05 represent the confidence level  

s^2 =16 represent the sample variance

\sigma^2_0 =25 represent the value that we want to  verify

System of hypothesis

We want to test if the true deviation for this case is lesss than 5minutes, so the system of hypothesis would be:

Null Hypothesis: \sigma^2 \geq 25

Alternative hypothesis: \sigma^2

The statistic is given by:

\chi^2 =\frac{n-1}{\sigma^2_0} s^2

And replacing we got:

\chi^2 =\frac{15-1}{25} 16 =8.96

The degrees of freedom are given by:

df = n-1 = 15-1=14

The p value for this case would be given by:

p_v =P(\chi^2

Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true deviation is not ignificantly lower than 5 minutes

Antwan Campbell earns $494 per week. He is married and claims 1 child as a dependent. The state tax rate is 2.25% of taxable inc
DENIUS [597]

Answer:

$12.35

Step-by-step explanation:

Amount earned by Campbell per week = $494

Tax rate = 2.25 %

Amount withheld = 2.25% of his earning;

Amount withheld = 2.25 % of 494

Amount withheld = 0.025 * 494

Amount withheld  = $12.35

Hence the amount withheld from his weekly pay for state income tax is $12.35
