Answer:
The 95% confidence interval estimate for the population mean force is (1691, 1755).
Step-by-step explanation:
According to the Central Limit Theorem if we have an unknown population with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from the population with replacement, then the distribution of the sample mean will be approximately normally.
The sample selected here is <em>n</em> = 30.
Thus, the sampling distribution of the sample mean will be normal.
Compute the sample mean and standard deviation as follows:

Construct a 95% confidence interval estimate for the population mean force as follows:


Thus, the 95% confidence interval estimate for the population mean force is (1691, 1755).
Answer:
i dont know bro
Step-by-step explanation:
1. The mean of all the numbers is 41.
5. Median : 52
5 equals 5/1. Simple as that.
Answer:
length times width times height
Step-by-step explanation:
width is height by the way
so 20×10×9 gives you 1800
1800 petrol can hold on Meters
