For this you would take the yellow circle and count the spot in a directions (6) and for blue you would do the same (2) so scale factor is 3
- a) An observation.
- b) A variable.
- c) A population parameter.
- d) A sample statistic.
Given that a survey asked the question, "Do you think a vaccination should be mandatory to enter shopping areas?" to a random sample of 1068 Jordanians, and the results showed that 71.2% responded that vaccination should mandatory, to determine which of the following is an observation, a variable, a sample statistic (value calculated based on the observed sample), or a population parameter, the following statistical reasoning must be performed:
(a) A Jordanian that was asked the question.
-An observation, as the person questioned is part of the study and therefore, it is an individual observation that makes up the trend.
(b) The response of the Jordanian.
-A variable, since it is one of the two possible answers that the survey has.
(c) 71.2%.
-A population parameter, because it represents a specific percentage with respect to the total population.
(d) The percentage of all Jordanians who agreed with the statement that vaccination should be mandatory to enter shopping areas.
-A sample statistic, since it is a statistical element that arises from the survey.

Answer: the amount in the account would be $515.15
Step-by-step explanation:
Initial amount deposited into the account is $500 This means that the principal is
P = 500
It was compounded quarterly. This means that it was compounded four times in a year. So
n = 4
The rate at which the principal was compounded is 4%. So
r = 4/100 = 0.04
The money would be compounded for 9 months. So
t = 9 months = 9/12 = 0.75
The formula for compound interest is
A = P(1+r/n)^nt
A = total amount in the account at the end of t years. Therefore
A = 500 (1+0.04/4)^ 4 × 0.75
A = 500(1.01)^3= $515.15
