Consider H0: μ = 45 versus H1: μ < 45. A random sample of 25 observations produced a sample mean of 41.8. Using α = .025 and
a_sh-v [17]
Given
H0: \ \mu=45 \\  \\ H1: \ \mu\ \textless \ 45
This is a one-tailed test.

z= \frac{41.8-45}{6/ \sqrt{25} } = \frac{-3.2}{6/5} = \frac{-3.2}{1.2} =-2.6667

P(z\ \textless \ -2.6667)=0.00383

Since the p-value of the sample statistic (0.00383) is less that the significant level (0.025), we reject the null hypothesis.

Answer:

25.9 yd

Step-by-step explanation:

a^{2} + {b^{2} }  = c^{2}

(17)^{2} + {b^{2} } = (31)^{2}

289 + {b^{2} }  = 961

Subtract 289 on both sides

{b^{2} }  = 672

\sqrt{b^{2} } = \sqrt{672}

nearest tenth

b = 25.9 yd
