It depends what your teacher wants it rounded to. It could be 300,000 if its rounded to the hundred thousands. If it is to the nearest hundred, it would be 384,300.
1)
a) 3/9= 0.333333333333 but you can just say 0.3
b) 4/3= 1.333333333333 but you also can say 1.33 or just 1.3
2)
a) 21/8, 21 over 8 if you solve you would get 2.625
b) 7(divide sign)4, which is also 7/4, if you solve you would get 1.75
c) 4/9 , 4 over 9 if you solve you would get 0.444444444 which is 0.4
d) 9/7, 9 over 7, if you solve it would be 1.285 which is 1.3
Divide to find the answer
Create the equation:
250-13x
Plug in 4 for the equation and solve:
250-13(4)
250-52
198
The answer is C. 198
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
