Marta measured the temperature as 65°f. what is the margin of error?
a . 60°f to 70°f
b .64°f to 66°f
c .64.5°f to 65.5°f
d .65.5°f to 66.5°f

Option C is correct.

Step-by-step explanation:

" Margin of error, mathematically speaking, is the range around any numerical answer that’s given in survey report and how closely the results represent the population on the whole ".

Marta measured the temperature as 65°F.

As in option C when we add and subtract 0.5 units in the measured temperature we get 64.5°F and 65.5°F.

Hence these are the most closely related value to 65°F.

While in other options the value are not so closely related.

Hence, margin of error is 64.5°F to 65.5°F.

Hence, option C is correct.
