8 0

Answer:

x₁ = 4

x₂ = 2

Step-by-step explanation:

x² - 6x + 8 = 0

x² - 2x - 4x + 8 = 0

x(x - 2) - 4(x - 2) = 0

(x - 4)(x - 2) = 0

x - 4 = 0 => x₁ = 4

x - 2 = 0 => x₂ = 2

Answer:

Test statistic (t) = 0.625

Step-by-step explanation:

Step(i):-

mean of the Population(μ) = 10.4 hours

Sample mean (x⁻) = 10.7 hours

Standard deviation of the sample( S) = 1.44

The level of significance (α= 0.1

Sample size 'n' = 9

Degrees of freedom = n-1 = 9-1 =8

Step(ii):-

Test statistic

$t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }$

$t = \frac{10.7 -10.4}{\frac{1.44}{\sqrt{9} } } =0.625$
