1200 employees of a company were surveyed to find out whether they were satisfies with the company's insurance policy. the survey showed that 80% of the respondents were not satisfied with the policy.
the standard error of the proportion is _%
the number of people who are satisfied with the policy if between _% and _%
all answers are appreciated you

Answer with explanation:

Sample Size = 1200

it is also given that 80% of the respondents were not satisfied with the policy,Means 20% of the respondents were satisfied with the policy.

80% of 1200=960

20% of 1200 =240

Standard error of the proportion

= 0.0115 (Approx)

=0.0115×100

=1.15%

→→20% of the respondents are satisfied with the policy.

So, the number of people who are satisfied with the policy is between 20-1.15=18.85% and 20+1.15=21.15% that is (18.85%,21.15%).

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
