The proportion of eligible voters in the next election who will vote for the incumbent is assumed to be 53.6%. What is the probability that in a random sample of 470 voters, less than 48.1% say they will vote for the incumbent

The required probability = 0.0084

Step-by-step explanation:

GIven that:

Sample proportion = 53.6% = 0.536

Sample size = 470

Then; the mean = n × p

mean = 470 × 0.536

mean = 251.92

Standard deviation =

Standard deviation =

Standard deviation =

Standard deviation =

Standard deviation = 10.81

The sample mean

The sample mean

The sample mean = 226.07

Thus;

= 0.0084

Therefore, the required probability = 0.0084

the answer is c. 23/3

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
