Step-by-step explanation:
Answer:
b. Sorted and listed from the minimum to the maximum values
Step-by-step explanation:
A percentile can be defined a measure that is made use of statistics.
A percentile is a statistical measure that indicates or shows comparison amongst a given set of data.
A percentile tells us the value or scores below which a percentage of a given observation in a data set falls.
In other to be able to effectively obtain the percentile if a given set of data, the following steps must be taken.
Step 1: Arrange, sort and list the values of the given the data set in order from lowest to the highest
Step 2: Multiply the percentage (also represented by P ) by total number of values in the data set( also represented by N)
Step 3: The value obtained from step 3 is know as the rank and this would helps us to find the percentile f a given data set.
The formula for calculating a percentiles is given as
= (P/100) x N,
where
P = percentile
N = number of values in a data set (sorted or arranged from lowest to highest)
n = Rank of a given value.
A 95% confidence interval for the proportion who believe immigration is a good thing is; CI = (0.4173, 0.7173)
<h3>What is the Confidence Interval of Proportions?</h3>
The formula for the confidence interval of proportions is;
CI = p ± z√(p(1 - p)/n)
where;
p is sample proportion
z is z-score at confidence level
n is sample size
We are given;
Number of success; x = 631
Sample size; n = 1095
Thus;
sample proportion; p = x/n = 631/1095 = 0.5763
The z-score at 95% confidence level is 1.96. Thus;
CI = 0.5673 ± 1.96√(0.5673(1 - 0.5673)/1095)
CI = 0.5673 ± 0.015
CI = (0.5673 - 0.15), (0.5673 + 0.15)
CI = (0.4173, 0.7173)
