Answer:
1.2
Step-by-step explanation:
Given that X is Normally distributed random variable with an unknown mean μ and known standard deviation 6
Hence we can say for a sample of size 100, the sample mean will have a std deviation of =
Since population std deviation is known we can use Z critical value for finding out the confidence interval
For 95% using (68-95-99.7 rules) we have z critical value =2
Hence margin of error =2(std error) = 1.2
Confidence interval 95%
Lower bound = Mean - margin of error = Mean -1.2
UPper bound = Mean +1.2
Hence , 95% of all of these values of x should lie within a distance of __1.2___ from μ .
I´m pretty sure that the terms would just be 3, 4, and 5. It depends what kind of problem it is.
The ratio of circumference to diameter of a circle is π, about 3.14. The diameter of the circular park will be about (62.8 m)/3.14 = 20 m.
The park is 20 m across at the widest point.
