liubo4ka [24]

Answer: 2.460

Step-by-step explanation:

The formula of Margin of Error for (n<30):-

$ME=t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

Given : Sample size : n= 18

Level of confidence = 0.90

Significance level : $\alpha=1-0.90=0.1$

Using the t-distribution table ,

Critical value : $t_{n-1, \alpha/2}=t_{17,0.05}= 1.7396$

Standard deviation: $\sigma=\text{ 6 inches }$

Then, we have

$ME=( 1.7396)\dfrac{6}{\sqrt{18}}\approx2.460$

Hence, the margin of error (ME) of the confidence interval with a 90% confidence level = 2.460

7:( 4/11 m)=56:3.2 solve.

vazorg [7]

Answer:

m= 1.1

Step-by-step explanation:

Given the question as 7:( 4/11 m)=56:3.2 this can be written as;

7: 4/11 m = 56 /3.2

7/4/11m = 560/32 ------------------perform cross multiplication

77*32=560*4/11m

224=2240/11 m

224=203.636 m--------------divide both sides by 203.636 to get m

224/203.636 = 203.636m/203.636

1.1 =m

Testing the value of m in the question

7: (4/11 *1.1) = 56:3.2

7:0.4 = 56 :3.2

70/4 = 560/32

17.5 =17.5
