A measure of the variation around the estimate of the mean.
The standard deviation is a statistic that lets you know how tightly all the subjects are clustered around the mean in a set of data. A single standard deviation away from the mean in either of the directions accounts for somewhere around 68 % of data. If two standard deviations are away from the mean, it accounts for around 95% of data. If three standard deviations are away it accounts for 99% of the data.
1) The total range of variation in the dataset is called RANGE.
3) A measure of the variation around the estimate of the mean is SEM (STANDARD ERROR OF THE MEAN).
4) The most common value observed (highest frequency) is MODE.
1. 24/(63%-59%)= 24/4%= 6,so the phone drop one charge every 6 minutes of listening to top pop.
42/6=7(the percentage consumed in 42 minutes)
46%-7=39%(percentage of battery left)
2. 76%-16%=50%(percentage of battery consumed after watching 3 episodes of "the haunted cave")
80x100%=8.000%(maximum percentage of battery at which the phone can be charged 80 times)
8000%/50=160(episodes of "the haunted cave" the monkey can watch)
3.idk the answer, sorry
Answer:
I=Prt
Step-by-step explanation:
The simple interest formula is given as;
I = Prt
where I is the simple interest
p is the principal
r is the percentage rate
t is the duration
Simple interest accrues on the principal of either a loan or an investment. This amount is payable after a duration of time.
Principal is the amount borrowed or invested in a business
Rate is the percentage commission to be paid on the amount borrowed
Time is the duration of the borrowing.
