We can find critical value by using t - table.
For using t - table we need degree of freedom and alpha either for two tailed test or one tailed test.
We can determine degree of freedom by subtracting sample size from one.
So in given question sample size is 23. So we can say degree of freedom(df) for sample size 23 is
df = 23 - 1= 22
Now we have to go on row for degree of freedom 22.
After that we need to find alpha either for two tailed test or one tailedl test.
Confidence level is 99%. We can convert it into decimal as 0.99.
So alpha for two tailed test is 100 - 0.99 = 0.01
Alpha for one tailed test is 0.01/2 = 0.005.
So we will go on column for 0.01 for two tailed test alpha or 0.005 for one tailed test alpha.
SO the critical value 22 degree of freedom and 0.01 two tailed alpha is 2.819 from t - table.

Answer:
7 flower bunches
Step-by-step explanation:
One flower bunch requires 12 roses since 48/4 is 12
then to find out how many flower bunches can be made by 84 roses you would have to divide 84 by 12 which gives you 7.
Answer:
B) 16 ft, 10.5 in
Step-by-step explanation:
There are a few different ways you can work this. Since we want to know the difference between length and heigh of the model and we are given skull length of the model, it makes a certain amount of sense to find the corresponding measurements of the actual skeleton.
The actual skeleton's length was 40 ft and its height was 13 ft, so the difference between these dimensions is ...
40 ft - 13 ft = 27 ft
The actual skull is 5 ft long, so the difference is ...
(27 ft)/(5 ft) = 5.4
times the length of the skull.
The same ratio will apply to the model, so the difference between the model height and model length is 5.4 times the length of the model skull:
desired difference = 5.4 × 3 ft 1.5 in = 16.2 ft + 8.1 in
= 16 ft 10.5 in
