True
Step-by-step explanation:
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
<span>The goal of writing a number in scientific notation is to have a decimal number, with one digit to the left of the decimal point, followed by a × 10 to some power.</span><span>To format your number in this way, we'll divide the 2967890052 by 10, 9 time(s), making it a 2.96789.
We do this, because each division by 10 moves the decimal point to the left one digit.
But in order to keep our number the same number, we must have a × 109 next to the 2.96789.</span><span>So, the final answer is 2.96789 × 10<span>9</span></span>
Each time you guess, you have a 1 in 10 chance of getting it correct. Doing this 4 times means you divide by ten each time you guess. This means you have a 1/10,000 chance of getting it correct.
