Days before a presidential election, a nationwide random sample of registered voters was taken. based on this random sample, it was reported that "52% of registered voters plan on voting for robert smith with a margin of error of plus or minus3%." the margin of error was based on a 95% confidence level. can we say with 95% confidence that robert smith will win the election if he needs a simple majority of votes to win?

No.

Step-by-step explanation:

Based on the sample, "52% of registered voters plan on voting for Robert Smith with a margin of error of plus or minus3%." The margin of error was based on a 95% confidence level.

Then 95% Confidence Interval is between 49% and 55%. Since confidence interval also includes non-majority proportions, the assumption that "95% confidence, Robert Smith will win the election" cannot be made.

it is not that hard all u have to do is plot the graph

step-by-step explanation:

x is the total time in minutes for the free response

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
