The second choice - 3.1%
All you have to do is multiply the probability by itself five times to get the total probability for the next five days.
1/2*1/2*1/2*1/2*1/2
= 1/2!
= 1/32
= 0.0313
= 3.13%
3.13 rounded off to the nearest tenth is 3.1%
There is 3.1% probability that Shania will arrive at school on time for the next five days.
Answer:
The IQR is a better measure of spread for dance competitions than for badminton games.
Step-by-step explanation:
I understand from "Dance Competition box plot has interquartile ranges approximately between 60 and 130" that quartile 1 is at 60 and quartile 3 is at 130, then, the interquartile range (IQR) is 130 - 60 = 70.
Similarly, from Badminton box plot, quartile 1 is at 90 and quartile 3 is at 150, then, the interquartile range is 150 - 90 = 60.
IQR is a measure of statistical dispersion, that is, as IQR increase, spread increase.
