This type or graph is used to show comparisons between values, with a bar representing each separate value. Categories or groups are commonly plotted on the horizontal axis (axis X) and a quantitative or numerical scale is plotted on the vertical axis (axis Y). Bar graphs are used to plot both continuous and discontinuous, or discrete, data.
advantages: show each data category in a frequency distribution, display relative numbers/proportions of multiple categories, summarize a large amount of data in a visual, easily intepretable form, make trends easier to highlight than tables do, estimates can be made quickly and accurately, permit visual guidance on accuracy and reasonableness of calculations, accessible to a wide audience
disadvantages: often require additional explanation, fail to expose key assumptions, causes, impacts and patterns, can be easily manipulated to give false impressions
Answer: (0.00306,0.00334)
Step-by-step explanation:
Given : Sample size : n= 420000
The number of users developed cancer of the brain or nervous system =134
Then , the proportion of users developed cancer of the brain or nervous system :
Significance level : 
Critical value : 
The confidence interval for population proportion is given by :-
Hence, the 90% confidence interval estimate of the percentage of cell phone users who develop cancer of the brain or nervous system is (0.00306,0.00334).
Suggartits it’s easy the answer is 3Baconatore 2 frosty free points bby
F(x)=2x³+x-3
f(-2)=2(-2)³+(-2)-3
f(-2)=2(-8)-2-3
f(-2)=-16-2-3
f(-2)=-18-3
f(-2)=-21. As a result,C is your final answer. Hope it help!
