Answer:
a) 18
b) 2.101
Step-by-step explanation:
a) What are the degrees of freedom for Student's t distribution when the sample size is 19?
Degrees of freedom = n - 1
Where n = sample size
= 19 - 1
= 18
b) Use the Student's t distribution to find tc for a 0.95 confidence level when the sample is 19.
(Round your answer to three decimal places.)
We would be determining these using the t distribution table
1 - 0.95 = 0.05 ( for two tailed)
Or
0.05/2 = 0.025(one - tailed)
Hence, the tc(test score) for a 0.95 confidence level when the sample is 19 is 2.101

Answer:
8 days until there will be only 4 cookies left in the jar
Step-by-step explanation:
36/4=9 cookies
the we subtract 1 because you still have four cookies left so your answer would be 9-1=8 cookies
Answer:
Step-by-step explanation:
y=3X+21
it meanss itt slope and y interceptt is postivee so it is increasing graph. Slope =3
Y Intercept =21
