RoseWind [281]

Answer:

the price of the package without the discount is $150

Step-by-step explanation:

The computation of the price of the package without the discount is shown below:

Let us assume the price without discount be x

So after discount it would be x - 0.12x = 0.88x

Now the equation would be

0.88x = $132

x = $132 ÷ 0.88

= $150

hence, the price of the package without the discount is $150

We simply applied the above formula so that the correct value could come

And, the same is to be considered

N =64
faust18 [17]

Answer:

B.  1.70

Step-by-step explanation:

Given:

  • n=64
  • \overline{x}=65.1
  • \sigma=24
  • \textsf{h}_0:\mu=60
  • \textsf{h}_1:\mu\neq 60

\textsf{If }\: X \sim\textsf{N}(\mu,\sigma^2)\:\textsf{ then }\: \overline{X} \sim \left(\mu,\dfrac{\sigma^2}{n}\right) \implies Z=\dfrac{\overline{X}-\mu}{\sigma / \sqrt{n}} \sim \textsf{N}(0,1)

\textsf{then test statistic is}: \quad z=\dfrac{\overline{x}-\mu}{\sigma / \sqrt{n}}

Substituting the given values into the formula to find the test statistic z:

\begin{aligned}\implies z &=\dfrac{65.1-60}{24 / \sqrt{64}}\\\\&=\dfrac{5.1}{3}\\\\&=\dfrac{17}{10}\\\\&=1.7\end{aligned}
