Answer:
Interquartile range = 24
Step-by-step explanation:
First we need to put the sequence in order from lowest to highest.
0, 1, 3, 5, 21, 25, 45
5 is the median and then from 5 to 0 we need to find the lowest interquartile in between it which is 1.
Highest interquartile from 5 to 45 finding the middle will be 25.
Interquartile range = highest interquartile - lowest quartile
25-1 = 24
Answer: 10r
Step-by-step explanation:
The car travels at a rate (r) and has the constant rate time 10 hours. r * 10 = 10r
Given:
Northern Florida: 2,000 patients ; 64% experienced flulike symptoms during December
Southern Florida: 3,000 patients ; 54% experienced flulike symptoms during December
Standard error = √[p(1-p)/n]
NF = √[0.64(1-0.64)/2000] = √[(0.64*0.36)/2000] = 0.0107 or 1.07%
SF = <span>√[0.54(1-0.54)/3000] = √[(0.54*0.46)/3000] = 0.0091 or 0.91%
smallest margin of error for a 95% confidence interval
NF: Em </span>≈ 0.98/√2,000 = 0.98/44.72 = 0.0219 or 2.19%
<span>SF: Em </span>≈ 0.98/√3,000 = 0.98/54.77 = 0.0178 or 1.78%

MY ANSWER:
</span><span>B.The southern Florida study with a margin of error of 1.8%.</span>
