Answer:
The right answer is:
"If 74% of Americans still favor mandatory testing this year, then there is a 1.5% chance that poll results will show 71% or fewer with this opinion."
Step-by-step explanation:
The P-value represents the probability of getting the sample we got, given that the null hypothesis is true. For this reason, it the P-value is lower than the significance level, it means that the sample result is unlikely due to chance, but due to a false null hypothesis.
In this case, the P-value represents a probability P=0.015 of having a sample with proportion p=0.71, given that the population has a proportion π=0.74.
The right answer is:
"If 74% of Americans still favor mandatory testing this year, then there is a 1.5% chance that poll results will show 71% or fewer with this opinion."
Answer:
C) The square root of terms separated by addition and subtraction cannot be calculated individually.
Step-by-step explanation:
sqrt(b² - 4ac) is not equal to
b - sqrt(4ac)
Because when you square b - sqrt(4ac), it's not b² - 4ac..
(b- sqrt(4ac))² = b² - 2bsqrt(4ac) + 4ac
