Step-by-step explanation:
The Hypothesis :
H0 : σ = 10
H1 : σ ≠ 10
The Chisquare statistic, χ² ;
χ² = [(n-1) * s²] ÷ σ²
Sample size, n = 44 ; sample Standard deviation, s = 10.7 ; population standard deviation, σ = 10
χ² = [(44 - 1) * 10.7²] ÷ 10²
χ² = [43 * 114.49] ÷ 100
χ² = [4923.07] ÷ 100
χ² = 49.2307
Using the Pvalue from Chisquare calculator :
degree of freedom, df = n - 1 = 44 - 1 = 43
Pvalue = 0.238
<em>The required equation is </em>
<em>2x + 16 = -24</em>
<em>=> 2x = -24 -16</em>
<em>=> 2x = -40</em>
<em>Dividing both sides by 2</em>
<em>x = -20</em>
The equations are y=3x-1 and y=-3x+5
I’ll try to solve it in the comments if you still have time
Answer: ln 20 + 5t
<u>Step-by-step explanation:</u>
ln (<em>ab</em>) = ln<em>a</em> + ln<em>b</em>
ln (10e⁵ˣ) = ln 10 + ln e⁵ˣ → (ln e cancels out)
= ln 10 + 5t
