In recent years the mean number of miles driven per year by residents of a particular state was 11,568. A researcher wishes to t
aleksandrvk [35]

Answer:

The degrees of freedom are given by:

df =n-1= 62 -1=61

And we want to find a critical value on the t distribution with 61 degrees of freedom who accumulates 0.025 of the area on each tail and the critical value would be t_{\alpha/2}= \pm 2.00

And the rejection region would be |t_{calc}| >2.00

Step-by-step explanation:

Data given and notation  

\bar X=10822 represent the sample mean  

s=1741 represent the sample standard deviation

n=62 sample size  

\mu_o =11568 represent the value that we want to test  

\alpha=0.05 represent the significance level for the hypothesis test.  

z would represent the statistic (variable of interest)  

p_v represent the p value for the test (variable of interest)  

State the null and alternative hypotheses.  

We need to conduct a hypothesis in order to check if the true mean differs from 11568, the system of hypothesis would be:  

Null hypothesis:\mu =11568  

Alternative hypothesis:\mu \neq 11568  

The degrees of freedom are given by:

df =n-1= 62 -1=61

And we want to find a critical value on the t distribution with 61 degrees of freedom who accumulates 0.025 of the area on each tail and the critical value would be t_{\alpha/2}= \pm 2.00

And the rejection region would be |t_{calc}| >2.00

PLEASE HURRY I ONLY HAVE 5MIN TO TURN IT IN!!! A new television set was recently purchased for a common Room and a resident Hall
mezya [45]

Answer:

The price of the tv before tax is 410

Step-by-step explanation:

Let x = price of tv before tax

tax = x*  9%

tax = .09x

The total cost is price of tv before tax plus tax

total cost = x + .09x

total cost = 1.09x

446.90 = 1.09x

Divide each side by 1.09

446.90/1.09 = 1.09x/1.09

410 = x

The price of the tv before tax is 410
