Assume that you want to test the claim that the paired sample data come from a population for which the mean difference is µd = 0. Compute the value of the t test statistic. Round intermediate calculations to four decimal places as needed and final answers to three decimal places as needed. x: 34 39 28 33 27 23 35 33y: 32 35 34 33 28 28 35 32a. t = -0.523b. t = -1.480c. t = 0.690d. t = -0.185

d: 2, 4, -6, 0, -1, -5, 0, 1

The second step is calculate the mean difference  

The third step would be calculate the standard deviation for the differences, and we got:

The next step is calculate the statistic given by :

And the correct option would be:

a. t = -0.523

Step-by-step explanation:

We assume the following notation:

x=test value after , y = test value before

x: 34 39 28 33 27 23 35 33

y: 32 35 34 33 28 28 35 32

The system of hypothesis for this case is given by:

Null hypothesis:

Alternative hypothesis:

The first step is calculate the difference and we obtain this:

d: 2, 4, -6, 0, -1, -5, 0, 1

The second step is calculate the mean difference  

The third step would be calculate the standard deviation for the differences, and we got:

The next step is calculate the statistic given by :

And the correct option would be:

a. t = -0.523

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
