Answer:

The t-value is 2.0049.

Step-by-step explanation:

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 55 - 1 = 54

Now, we have to find a value of T, which is found looking at the t table, with 54 degrees of freedom(y-axis) and a confidence level of 0.95(t_{95}). So we have T = 2.0049

The t-value is 2.0049.

Write the number 5267 correct to<br> the nearest hundred.
galben [10]

Answer:

5300.

If you're rounding to the nearest hundred you look at the tens place. If its 5 or over you go up. So in this case we'll raise the 2 to a 5 because 6 is above 5.
