g100num [7]

Answer: (24.28,\ 27.72)

Step-by-step explanation:

Given : Sample size : n=50

Sample mean : \overline{x}=26

Standard deviation : \sigma =6.2

Significance level : \alpha=1-0.95=0.05

Critical value : z_{\alpha/2}=1.96

Formula to find the confidence interval for population mean :-

\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\=26\pm(1.96)\dfrac{6.2}{\sqrt{50}}\\\\\approx26\pm1.72\\\\=(26-1.72,\ 26+1.72)\\\\=(24.28,\ 27.72)

Hence, a 95% confidence interval for the population mean = (24.28,\ 27.72)

How do I do this problem?
lyudmila [28]
To do this, you have to solve the length, width, and height and then round the answer to the nearest hundredth. Since it says round to the nearest HUNDRETH then I'm guessing that you have to get the LxWxH as a hundredth value.

Operation for <br><br>w/7 = 14<br><br>addition<br>subtraction<br>multiplication<br>division​
NikAS [45]

Answer: Multiplication

Step-by-step explanation:

Given

w/7=14

Multiply 7 on both sides

w/7 × 7=14 × 7

w=98

In order to isolate w on one side, we should times 7 as the numerator in order to eliminate the 7 in the denominator. To promise equality, we need to multiply 7 on both sides in order to isolate w and solve the equation.

<h2>Thus, it is multiplication.</h2>
