Answer:
1.414
Step-by-step explanation:
(-5, -3) (-4,-2)
√(x2 - x1)² + (y2 - y1)²
√[-4 - (-5)]² + [-2 - (- 3)]²
√(1)² + (1)²
√(1) + (1)
√2
= 1.414

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."
