Answer:
a. 0.1917
b. 0.0914
d. 0.1580
Step-by-step explanation:
(a)
Mean, 
= 0.375 -0.1833 = 0.1917
(b) sample prop ? Show your work and label each value.
Mean, = = 0.1917
Standard deviation = 
Standard deviation = 
Standard deviation = 0.0914
(c)
Normality condition:
np ≥ 10 and n(1-p) ≥ 10
Both the samples satisfy the normality condition.
(d)
The probability is obtained by calculating the z score,
= 1.0029
P(z > 1.0029) = 1 - P(z ≤ 1.0029)
The probability is obtained from the z distribution table,
P(Z > 1.0029) = 1 - 0.8420 = 0.1580
Answer:
1) 3.21 by itself if rational, I don't know if the dots mean anything, but if they do, then it is irrational.
2) Pi is an irrational number as it repeats forever.
Yes it describes only a parameter because <span>a numerical characteristic of a population, as distinct from a statistic of a sample was use. only 35 out of the 1200 accountants salary was used in calculating an average salary. it will be real if use all the number of accountant in calculating the average salary</span>
