In a sample of 83 walking canes, the average length was found to be 34.9in. with a standard deviation of 1.5. give a point estimate for the population standard deviation of the length of the walking canes. round your answer to two decimal places, if necessary.

The point estimate for the population standard deviation of the length of the walking canes is 0.16.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , a large sample size can be approximated to a normal distribution with mean and standard deviation .

In this problem

The point estimate of the standard deviation is the standard deviation of the sample.

In a sample of 83 walking canes, the average length was found to be 34.9in. with a standard deviation of 1.5. By the Central Limit Theorem, we have that:

The point estimate for the population standard deviation of the length of the walking canes is 0.16.

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
