kotykmax [81]

Answer:

$114.3

Step-by-step explanation:

Number of hours worked last week = 12hrs

Amount earned for her work hours = $98

The rate at which she earned = ?

Rate = $\frac{amount earned }{total work hour}$

Rate = $\frac{98}{12}$ = $8.17/hr

Ivan

Answer: $\pm0.1706$

Step-by-step explanation:

Given : Sample size : n= 33

Critical value for significance level of $\alpha:0.05$ : $z_{\alpha/2}= 1.96$

Sample mean : $\overline{x}=2.5$

Standard deviation : $\sigma= 0.5$

We assume that this is a normal distribution.

Margin of error : $E=\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

i.e. $E=\pm (1.96)\dfrac{0.5}{\sqrt{33}}=\pm0.170596102837\approx\pm0.1706$

Hence, the margin of error is $\pm0.1706$
