What is the midpoint of (-7,-9) (6,3)
Advocard [28]

Answer :

Let the first term of both the terms be \:  \sf \: x _1 \:  \: \& \:  \: x _2 and last term be \:  \sf \: y _1 \:  \: \& \:  \: y_2\\

Now, by using the mid point formula to find the mid point of the segment -

\\   \sf \bigg( \frac{x_1 + x_2}{2} , \:  \frac{y_1 + y_2}{2}  \bigg) \\

Now, by substituting the values of both x and y -

\\  \sf \bigg( \frac{ - 7 + 6}{2} , \:   \frac{ - 9 + 3}{2}  \bigg) \\

Adding -7 and 6 -

\\  \sf \bigg( \frac{ - 1}{2} , \frac{ - 9 + 3}{2}  \bigg) \\

Now, move the negative in front of the fraction -

\\  \sf \bigg( \frac{ - 1}{2} , \frac{ - 6}{2}  \bigg) \\  \\  \\  \sf \bigg( \frac{ - 1}{2} , - 3\bigg) \\

As level of Confidence interval increases width of interval increases.

Width of interval \propto  level of Confidence interval

So, If a 95% confidence interval had been constructed instead of 90% the width of the interval would have been<u> increased.</u>
