Answer:
For α=0.01 and two-tailed test: t=2.8188
For α=0.025 and two-tailed test: t=2.4055
For α=0.05 and two-tailed test: t=2.0739
For α=0.10 and two-tailed test: t=1.7171
Step-by-step explanation:
In this problem, we have to estimate the value of the statistic "t" of a sample of size n=23 (22 degrees of freedom), in which the sample mean is M=770 and the sample standard deviation is s=25.
The estimated standard deviation is
The critical values of the statistic t depends on the significance level:
The degree of freedom is known: df=22.

Answer:
36cm^2
Step-by-step explanation:
Break it apart into rectangles/squares where you can figure out what the length of at least two sides are for each.
Then multiply and get the area of the smaller area.
Then add the areas up.
You're basically just breaking it down into smaller shapes, then adding the different parts back together.
