I think it's 15 because 6, 7, and 8 are one after the other in order, and 15 is far away from 6, 7, and 8.

Hope this helped☺☺

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}
