Yes one is a probability because it can be one out of 4 or something
Good luck hope this helps
False. To make nine, you must multiply three by three. Four times three isn’t 8. An equivalent equation would be 4/3=12/9
Answer:
a) The estimated standard deviation of the sampling distribution of the proportion is 0.023
b) the estimated standard deviation have been if he had surveyed only 100 customers is 0.046
Step-by-step explanation:
given information:
the number of sample, n = 400
sample proportion, p = 70% = 0.7
a) standard deviation of a sample proportion is
σ = 
= 
= 0.023
b) if n = 100, so
σ = 
= 
= 0.046

Answer:

Step-by-step explanation:
step 1
Find the slope
The formula to calculate the slope between two points is equal to

take two points from the data
(0,8), and (8,-24).
substitute



step 2
Find the equation of he line in slope intercept form

we have

----> the y-intercept is given
substitute
