Answer: b= 58a (divided 348 by 6 and take the equation b = ka and substitute k with 58)
Ok first add all of the results together 44+55+55+66=220 Then found out how many percent each number is of 220. 44 is 20% of 220, 55 is 25%, 55 is 25%, 66 is 30%
Answer:
Sample proportion ; phat
x / n
Step-by-step explanation:
The sample proportion may be explained as a proportional representation of part of the population or larger sample which have a certain character or exhibit a particular trait.
The sample proportion is expressed Mathematically as ;
phat = x / n
x = number of subjects with a specified characteristic ;
n = total sample size
For instance ;
The proportion of black balls in a sample of 100 balls is 15 ; the sample proportion of bla k balls will be :
phat = x / n = 15 / 100 = 0.15
