1 answer:
Answer:
Step-by-step explanation:
Ok, so the equation so find the circumference of a circle is C = 2
So we can fill in the variable for radius as we know it is 8. The equation show know look like this:
Now we just need to multiply the numbers 2 and 8 together.
So, because we leave the answer in terms of pi, we're done! :)

Answer:
For the first group, with 19 degrees of freedom, the critical value is t=2.093.
For the second group, with 21 degrees of freedom, the critical value is t=2.080.
Step-by-step explanation:
The critical value of the t-statistic depends on the significance level and the degrees of freedom of the sample.
For a significance level of 0.05, for a two-tailed test, there is an upper 2.5% and a lower 2.5%.
For the first group, with 19 degrees of freedom, the critical value is t=2.093.
For the second group, with 21 degrees of freedom, the critical value is t=2.080.
