Answer:
Given:
mean, u = 6.2
sample size, n = 180
Sample mean, X' = 6.3
s.d 
= 0.9
Significance level = 0.05
The null and alternative hypothesis will be:
H0 : u = 6.2
H1 : u > 6.2
Degree of freedom = 180 - 1 = 179
Using t table, the t critical value,
t> t(0.05, 179) = 1.6534
The test statistic:
Since the test statistic(t calculated value) 1.4907 < t critical value (1.6534), we fail to reject the null hypothesis H0.

Answer:
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
10% = 10/100 = 10 ÷ 100 = 0.1.
100% = 100/100 = 100 ÷ 100 = 1.
Increase the number by 10% of its value.
Percentage increase = 10% × 2,880
New value =
2,880 + Percentage increase =
2,880 + (10% × 2,880) =
2,880 + 10% × 2,880 =
(1 + 10%) × 2,880 =
(100% + 10%) × 2,880 =
110% × 2,880 =
110 ÷ 100 × 2,880 =
110 × 2,880 ÷ 100 =
316,800 ÷ 100 =
3,168
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 2,880 =
3,168 - 2,880 =
288
Step-by-step explanation:
- The <u>relationship</u> between <em>absorbance and concentration is known as the </em><em>Beer-Lambert Law</em><em>.</em>
- This <u>relationship</u> is linear, meaning that <em>absorbance is directly proportional to concentration</em>.
- The <u>absorbance</u><u> of a </u><u>solution</u> is directly <em>proportional to the concentration of the </em><em>light-absorbing</em><em> species</em> in the solution.
<h3>The Relationship Between Absorbance and Concentration</h3>
As the concentration of a light-absorbing species in a solution increases, the absorbance of the solution also increases. <u>This relationship is known as the </u><u>Beer-Lambert Law</u><u>. </u>
- The Beer-Lambert Law states that absorbance is directly proportional to concentration. This means that as the concentration of a light-absorbing species in a solution increases, the absorbance of the solution also increases.
- This relationship is linear, meaning that there is a direct relationship between absorbance and concentration.
- The absorbance of a solution is directly proportional to the concentration of the light-absorbing species in the solution.

This equation is written in point-slope form.
In this equation we have the point (2, 12) and the slope of 4.
Slope-intercept form: y = mx + b
m = slope
b = y-intercept
Use the point (2, 12) to solve.
12 = 4(2) + b
12 = 8 + b
12 - 8 = 8 + b - 8
4 = b (y-intercept)
