39 minutes lef someoneeethe table shows the number of hours spent studying for a history final exam and the score on that exam. each row represents a single student. which value is an outlier in the table below? exam scores number of hours spent studying, x exam score (out of 100), y 1.5 65 2 68 3.5 71 4.5 98 4.5 82 6 84 6.5 88 7 85 7 80 a. (1.5, 65) b. (3.5, 71) c. (4.5, 98) d. (6.5, 88)

For it to be an outlier in this problem, it would mean that the score for every hour studied would be wildly inconsistent from the rest of the dataset. We see that every one of them is around 15-20, but then we have (1.5,65) which yields 43 points per hour, which is very inconsistent with the rest of the data which leads us to say that A is our outlier.

C)  (4.5, 98)

Step-by-step explanation:

Outliers are easy to find, they just have to be farther away from the cluster(s) of data in general.

So, I made a scatterplot based on the exam scores and this is what I got:

The outlier is (4.5,98)

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
