Why is sample size important in experimental design? A. Larger sample sizes increase the likelihood that the sample is a good re
nlexa [21]

Answer: A

Step-by-step explanation: when Constructing a confidence interval, it is important to take note of the margin of error which is given by the formulae below

Margin of error = critical value × σ/√n.

Where n is the sample size.

As we can see that the critical value is a constant and the population standard deviation.

Hence there is an inverse relationship between margin of error and sample size, which implies that a large sample size produces a small margin of error.

If the margin of error is small, it means the sample size will increase the like hood that the sample is a good representation of the population.

Evaluate the function g(x) = –2x2 + 3x – 5 for the input values –2, 0, and 3. G(–2) = –2(–2)2 + 3(–2) – 5 g(–2) = –2(4) – 6 – 5
12345 [234]

Answer:

Step-by-step explanation:

g(x)= -2 x^2 + 3 x - 5

g(-2) = -2 . (-2)^2 + 3. (-2) - 5 = -2 . 4 - 6 - 5 = - 8 - 6 - 5 = - 19

g(0) = -2 . (0)^2 + 3 . 0 - 5 = -2 . 0 + 0 - 5 = 0 + 0 - 5 = - 5

g(3) = -2 . (3)^2 + 3 . (3) - 5 = -2 . 9 + 9 - 5 = -18 + 9 - 5 = - 14
