Answer:
0.04
Step-by-step explanation:
In this case we must use the following formula to be able to find the standard error, which would be the square root, of the probability for its complement divided by the population:
SE=
Now, knowing that p = 0.552 and n = 160 we replace and we are left with:
SE =
SE =
SE = 0.039
Which means that the standard error of the proportion is 0.04
Given that the basket of watermelons sells for $9 before tax and the tax rate is 9%.
The tax on the basket of watermelons is given by
Therefore, the total price Tiffany pays for the basket of watermelons is $9 + $0.81 = $9.81
