Answer to this math question

gladu [14]

Answer:

$4\frac{2}{3}$

Step-by-step explanation:

This is a recurring decimal.

Let x = 4.666666... ⇒ (1)

10x = 46.66666... ⇒ (2)

Subtract equation (1) from equation (2)

10x = 46.66666..

-<u> x = 4.666666... </u>

<u> 9x = 42.0000.....</u>

<u />

9x = 42

x = 42/9

= 14/3

= $4\frac{2}{3}$

The mean is the average . the sum of number over the number of observation

x1=525

x2=487

s.d1=59.42

s.d2=51.74

n1=16

n2=12 $\alpha =0.05$

Determine the hypothesis

$H_{0}:$ u1≤u2

$H_{a} :u1>u2$

find the degree of freedom $(\frac{s1^2}{n1} +\frac{s2^2}{n2} )^2/(\frac{s1^2}{n1} )^2/n1-1+(s2^2/n2)^2/n2-1\\\\(\frac{59.42^2}{16} +\frac{51.7476^2}{12} )^2/(\frac{59.42^2}{16} )^2/16-1+(51.74^2/12)^2/12-1$

0.025<P<0.05

if the P value is actually less than or the same as the significant level, then the null hypothesis is rejected

P<0.05 rejected H
