1. 18 = 3/4(y+8)-3

18 = 3/4y+6-3

18 = 3/4y+3

3/4y = 15

y = 20

2. 1/2(x+4)+1/2(x+4)=8 ---> (1/2+1/2)(x+4)=8 (quick trick :))

(1)(x+4)=8

x+4=8

x=4

3. 1/2(2x+6)+x=1

x+3+x=1

2x+3=1

2x=-2

x=-1

Answer:

The 95% of confidence intervals

(2.84 ,2.99)

Step-by-step explanation:

A random sample of 20 accounting students results in a mean of 2.92 and a standard deviation of 0.16

given small sample size n =20

sample mean x⁻ =2.92

sample standard deviation 'S' =0.16

level of significance ∝ = 0.95

The 95% of confidence intervals

$x^{-} ± t_{\alpha } \frac{S}{\sqrt{n} }$

the degrees of freedom γ=n-1 =20-1=19

t-table 2.093

$(x^{-} - t_{\alpha } \frac{S}{\sqrt{n} },x^{-} + t_{\alpha } \frac{S}{\sqrt{n} })$

$(2.92 - 2.093(\frac{0.16}{\sqrt{20} } ,2.92+2.093(\frac{0.16}{\sqrt{20} } )$

(2.92-0.0748,2.92+0.0748)

(2.84 ,2.99)

Therefore the 95% of confidence intervals

(2.84 ,2.99)
