The temperature in a certain location was recorded each day for two months. The mean temperature was 66F with a standard deviation

9.2 F. What can you determine about these data by using Chebyshev's Inequality with K=3?

It wants me to find "At least Blank % of the days had temperatures between blank F and blank F.

I just can't seem to figure this out.

Second Question:

Nuclear power: The following table presents the number of nuclear reactors as of August 2 2013 in some countries that had one or more reactors.

Country	Number of Reactors	Country	Number of Reactors
Argentina	2	Iran	1
Armenia	1	Japan	50
Belgium	7	Russia	33
Brazil	2	Slovakia	4
Bulgaria	2	Slovenia	1
Canada	19	South Africa	2
China	18	Spain	8
Czech Republic	6	Sweden	10
Finland	4	Switzerland	5
France	58	Ukraine	15
Germany	9	United Kingdom	16
Hungary	4	United States	100
India	20

It wants me to find the 45th Percentile and the 88th percentile.

The third one I am confused on:

For the data set

1	3	4	4	6	8	9	9	12	12
13	15	15	16	16	16	17	18	19	20
24	24	24	24	25	25	26	27	27	28
31	31	34	34	34	35	35	39	39	43
45	45	46	48	48	51	52	52	52	55

It wants me to find the 76th, 45th, 17th and 66th percentile.

This one I am a little lost as well on.
