Using the t-distribution, it is found that the 99% confidence interval for the difference is (0.058, 3.462).
We are given the <u>standard deviation for the samples</u>, hence, the t-distribution is used to solve this question.
The standard errors are given by:
For the distribution of differences, the <u>mean and the standard error</u> are given by:
The interval is given by:
The critical value for a <u>two-tailed 99% confidence interval</u> with 18 + 18 - 2 = <u>34 df</u> is t = 2.7284.
Then:
The 99% confidence interval for the difference is (0.058, 3.462).

Answer: 108
lmk if this is wrong
Step-by-step explanation:
V=1/3bh
V=1/3(1/2bh)(h)
V=1/3(1/2)(9)(6)(12)
(i simplified)
V=(1)(1)(3)(6)(6)
V=108
Answer:
The value of x will be:
Step-by-step explanation:
Given the equation
Multiply (or distribute) each term in parenthesis on L.H.S by -2, and multiply (or distribute) each term in parenthesis on R.H.S by 3.
simplifying the equation by subtracting 14 from the L.H.S
Subtracting 15 from both sides
combining the like terms
dividing both sides of the equation by 5
Therefore, the value of x will be:
