Answer:
μ = 1.3468
Step-by-step explanation:
Given data:
Observations
0.85
0.88
0.88
1.06
1.09
1.12
1.29
1.31
1.42
1.49
1.59
1.62
1.65
1.71
1.76
1.83
sum of the observations = 21.55
now,
the total number of the given data, n = 16
now, the mean is given as:
Mean = (Sum of all the observation) / (Total number of observations)
on substituting the values in the above formula, we get
Mean = 21.55 / 16
or
Mean = 1.3468
Since, it is given that the data follows normal distribution.
thus, the normal mean can be used as the point of estimator (μ)
i.e μ = 1.3468
Answer:
I believe that the answer is C.
Step-by-step explanation:
You can divide the numerator and denominator each by 3.
5 can simplify 15, but it can't 9.
9 / 3 = 3
15 / 3 = 5
9/15 simplified is 3/5.
-3/5 divided by 7/6 is -18/35
