a 90% confidence interva is constructed for the population mean. If a 95% confidence interval had been constructed instead (everything else remaining the same), the width of the interval would have been__and the p

increased

Step-by-step explanation:

More level of confidence more width of the interval.

As level of Confidence interval increases width of interval increases.

Width of interval  level of Confidence interval

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

could you reply to this with the question so i can ?

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
