Answer:
The point estimate for p is 0.86.
Step-by-step explanation:
We are given that in a marketing survey, a random sample of 730 women shoppers revealed that 628 remained loyal to their favorite supermarket during the past year (i.e. did not switch stores).
Let p = <u><em>proportion of all women shoppers who remain loyal to their favorite supermarket</em></u>
Now, the point estimate for the population proportion (p) is represented by ;
Point estimate for p =
=
where, X = Number of women shoppers who remained loyal to their favorite supermarket during the past year = 628
n = sample of women shoppers = 730
So, <u>point estimate for p</u> (
) =
=
= <u>0.86</u>
Answer:
Step-by-step explanation:
-x + 5 = 5x - 6
-6x + 5 = -6
-6x = -11
6x = 11
x = 11/6
-11/6 + 30/6= 19/6
(11/6, 19/6)
answer is C
Given:


Multiply both sides by 3/2, we get

Cancel out the common multiples, we get



The solution of the given equation is

or
Y= 13x+4x
y equals the amount of money spent
Answer:
B) 0.01
Step-by-step explanation:
If they want to know which one is very unlikely, you could turn them into percents.
1=100%
0.01=1%
0.9=90%
0=0%
0.6=60%
0.5=50%
0.35=35%
Since 0% is "impossible", not just "very unlikely", I'd go with 1%, which is B) 0.01
This is assuming I'm understanding your question correctly, since it doesn't actually ask a question.
