Answer:
Incorrect
Step-by-step explanation:
This interpretation is incorrect because it states that 98% of the data is with in the confidence interval.
or 98% of the laptop have screen size between 19.2 and 21.4 inches
However, the interpretation would have been correct if it would have stated as - Value of the population mean i.e mean size of the laptop screen lies within the confidence interval.
=-30
-2*-3=6
-1*5=-5
6 x -5=-30
10/14 = 5/7.
5/7 is your answer. Divide both the numerator and the denominator by a number that they both have in common - 2.
