32 cm is the length of PQ ans
Let Z be a random variable following the standard normal distribution with mean µ = 0 and standard deviation σ = 1.
The 67th percentile of the distribution is the value z that separates the bottom 67% of the distribution from the top 100% - 67% = 33%. In terms of probability, we have
Pr[Z ≤ z] = 0.67
Use the inverse CDF for the normal distribution (or lookup z scores in a table) to find
z = ɸ⁻¹(0.67) ≈ 0.4399
where ɸ(z) is the CDF for the normal distribution.
Add the numbers from the three sliders to determine the mass
Drawing a conclusion from the graph, the true statement from the option given is <em>Voter turnout in national election years is irregular from 2006 to </em><em>2020</em><em>.</em><em> </em>
Voter turnout in 2006 was 40% while in 2014 it was 35% `; hence, voters were more interested in 2006 than in 2014.
In some of the years given, less than 50% of Americans participated in the polls.
Hence, the true statement is <em>"</em><em>Voter turnout in national election years is irregular from 2006 to </em><em>2020</em><em>"</em><em> </em>
