Researchers studying the effect of diet on growth would like to know if a vegetarian diet affects the height of a child. Twelve

Eva8 [605]

Answer:

a) $t_{0.035},11=\pm2.201$

b) $t=-2.963$

c) $Reject\ H_0\ when\ \alpha=0.05$

d) $t$

$-2.963$

Step-by-step explanation:

From the question we are told that:

Sample size $n=12$

Mean $\=x=42.5$

Standard deviation $\sigma=3.8$

Population mean $\mu=45.75$

Significance $\alpha=0.05$

Generally the hypothesis given by

$H_0;\mu=45.75\\H_1:\neq =45.75$

Generally the equation for test statistics is mathematically given by

$t=\frac{\=x-\mu}{\sigma/\sqrt{n} }$

$t=\frac{42.5-45.75}{3.8/\sqrt{12} }$

$t=-2.963$

Generally the Critical value is mathematically given by

$t_{\alpha/2},d_t$

$\alpha=0.05 \\\alpha/2=0.025\\d_t=n-1=11$

$t_{0.035},11$

From table

$t_{0.035},11=\pm2.201$

Therefore

$t$

$-2.963$

$Reject\ H_0\ when\ \alpha=0.05$

$Answer: \\GK\: bisects\: \widehat{FGH} \Rightarrow \widehat{FGK} =\widehat{HGK} \\ \widehat{FGH} = \widehat{FGK} + \widehat{HGK} = 2\widehat{FGK} \\ \Leftrightarrow 104 =2( 7w + 3 ) \\ \Leftrightarrow 14w + 6 = 104 \\ \Leftrightarrow 14w = 98\Leftrightarrow w = 7$
