Sienna was dividing 12.76 by 0.001.Let's find out which one is correct based on the given choices. Let's perform division
=> 12.76 / 0.001 = 12 760
Thus, the correct answer is B. It will be less than 13,000.
Answer:
a) P(X≥143)=0
b) This contradicts the study as getting a sample with this proportion is almost impossible (if the proportion of 68% is true).
Step-by-step explanation:
If we use the normal approximation to the binomial distribution we have the following parameters (mean and standard deviation):

Then, we can calculate the probability of X being equal or more than 143 using the z-score:

This contradicts the study as getting a sample with this proportion is almost impossible (if the proportion of 68% is true).
Answer: 18
Step-by-step explanation:
Square root of 81 is 9 because 9*9=81 then 9*2=18
