The standard deviation for actuary salaries has a standard deviation of $36,730 . You collect a simple random sample of n=36 sal

Yanka [14]

Using the z-distribution, it is found that the lower limit of the 95% confidence interval is of $99,002.

<h3>What is a z-distribution confidence interval?</h3>

The confidence interval is:

$\overline{x} \pm z\frac{\sigma}{\sqrt{n}}$

In which:

$\overline{x}$ is the sample mean.

z is the critical value.

n is the sample size.

$\sigma$ is the standard deviation for the population.

In this problem, we have a 95% confidence level, hence $\alpha = 0.95$ , z is the value of Z that has a p-value of $\frac{1+0.95}{2} = 0.975$ , so the critical value is z = 1.96.

The other parameters are given as follows:

$\overline{x} = 111000, \sigma = 36730, n = 36$

Hence, the lower bound of the interval is:

$\overline{x} - z\frac{\sigma}{\sqrt{n}} = 111000 - 1.96\frac{36730}{\sqrt{36}} = 99002$

The lower limit of the 95% confidence interval is of $99,002.

Is 1 5/8 greater than, less than, or equal to 1.6?

tigry1 [53]

Answer:

$1 \frac{5}{8} > 1.6$

Step-by-step explanation:

$1 \frac{5}{8} \: ... \: 1.6$

$\frac{1 \times 8 + 5}{8} \: ... \: 1.6$

$\frac{8 + 5}{8} \: ... \: 1.6$

$\frac{13}{8} \: ... \: 1.6$

$\frac{13}{8} \: ... \: \frac{16}{10}$

$\frac{13 \times 5}{8 \times 5} \: ... \: \frac{16 \times 4}{10 \times 4}$

$\frac{65}{40} \: ... \: \frac{64}{40}$

$\frac{65}{40} > \frac{64}{40}$

X=9y<br> 5x+3y= -48<br> What does x equal?<br> What does y equal?

Anon25 [30]

you can plug the x value (9y) into the second equation

5(9y) + 3y = -48

45y + 3y = -48

48y = -48

y = -1

x = 9(-1)

x = -9

Where should the x be????

Eduardwww [97]

There should be an X over 9.6, 0, √16, and 2.45.

9.6 = Integer
0 = Whole Number
√16 (or 4) = Counting Numbers
2.45 = Integer

P2 + 4p - 12 = 0 Find the value of the discriminant. A) 2 B) 4 C) 8 D) 64

Nezavi [6.7K]

Answer:

Step-by-step explanation:

given p² + 4p - 12 = 0 ← in standard form

with a = 1, b = 4, c = - 12, then the discriminant

Δ = b² - 4ac

= 4² - (4 × 1 × - 12) = 16 - (- 48) = 16 + 48 = 64 → D
