Explanation:
This data set shows the ages of the last 12 winners of a
prestigious film award for Actress in a Leading Role.
61, 32, 33, 45, 29, 62, 22, 44, 54, 26, 28, 60
Calculate the statistics of mean and standard deviation
of the data set. Round to the nearest hundredth, if
necessary.
O mean 38.50 and standard deviation - 14.89
O mean 38.50 and standard deviation = 40
O mean = 41.33 and standard deviation = 40
mean 41.33 and standard deviation - 14.89
Answer:
D. mean is 41.33, and standard deviation is 14.89
Explanation:
Given the data set: 61, 32, 33, 45, 29, 62, 22, 44, 54, 26, 28, 60 of 12 winners.
i. The mean of the data set = [tex]\frac{sum of data set}{number of data set}[/tex]
= [tex]\frac{61 + 32 + 33 + 45 + 29 + 62 + 22 + 44 + 54 + 26 + 28 + 60}{12}[/tex]
= [tex]\frac{496}{12}[/tex]
= 41.3333
The mean of the data set = 41.33
ii. Standard deviation = [tex]\sqrt{\frac{Sum(x_{i} - U) ^{2} }{N} }[/tex]
Where: [tex]x_{i}[/tex] is the value of each data set given, U is the mean, N is the number of data set.
Sum ([tex]x_{i}[/tex] - U) = [tex](61 - 41.33)^{2}[/tex] + [tex](32 - 41.33)^{2}[/tex] + [tex](33 - 41.33)^{2}[/tex] + [tex](45 - 41.33)^{2}[/tex] + [tex](29 - 41.33)^{2}[/tex] + [tex](62 - 41.33)^{2}[/tex] + [tex](22 - 41.33)^{2}[/tex] + [tex](44 - 41.33)^{2}[/tex] + [tex](54 - 41.33)^{2}[/tex] + [tex](26 - 41.33)^{2}[/tex] + [tex](28 -41.33)^{2}[/tex] + [tex](60 - 41.33)^{2}[/tex]
= 386.91 + 87.05 + 69.39 + 13.47 + 152.03 + 427.25 + 373.65 + 7.13 + 160.53 + 235.01 + 177.69 + 348.57
= 2438.68
Standard deviation = [tex]\sqrt{\frac{2438.68}{12} }[/tex]
= 14.26
Therefore, the statistics mean is 41.33 and standard deviation is 14.89

In which type of US election is it possible for the winning candidate to get fewer popular votes than the opposing candidate
A. most state government elections
B. House elections
C. Senate elections
D. most local government elections
E. presidential elections
Answer:
The correct answer is E)Presidential elections.
The presidential election is not determined by popular vote. Rather, it is determined by a system known as the electoral college. The electoral college system involves each state having a certain number of electoral votes roughly based on their population size. In this system, states with larger populations have more electoral votes.
In the electoral college, a candidate must receive 270 electoral votes in order to become president. If a candidate reaches this threshold they win, regardless of the popular vote results.
All of the other elections mentioned in the answer choices are determined by popular vote.
