Suppose you have a sample of size 42 with a mean of 30 and a population standard deviation of 7.4. What is the maximal margin of

9966 [12]

Answer:

The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.

Step-by-step explanation:

We have given,

The sample size n=42

The sample mean $\bar{x}=30$

The population standard deviation $\sigma=7.4$

Let $\alpha$ be the level of significance = 0.05

Using the z-distribution table,

The critical value at 5% level of significance and two tailed z-distribution is

$\pm z_{\frac{0.05}{2}}=\pm 1.96$

The value of margin of error is

$ME=z_{\alpha/2}(\frac{\sigma}{\sqrt{n}})$

$ME=1.96(\frac{7.4}{\sqrt{42}})$

$ME=1.96(1.1418)$

$ME=2.238$

The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.

The length of a rectangle is 5 inches more than twice a number.The width is 4 inches less than the same number.If the area of th

umka2103 [35]

Answer:

n = 5, n = -7/2

Step-by-step explanation:

2n + 5 = l

n - 4 = w

A = l × w = 15

(2n + 5)(n-4) = 15

2n^2 - 8n + 5n - 20 = 15

2n^2 -3n - 35 = 0

(2n + 7)(n - 5) = 0

2n + 7 = 0 or n - 5 = 0

n = -7/2 or n = 5
