Answer:
2.42
Step-by-step explanation:
We are asked to consider a sample of blades for a circular saw, and their diameters were measured.
We are told they have a sample of variance, S²= 2.42
We are told to give a point estimate for the population variance in diameters of blades for the circular saw.
The sample variance, S² can be said to be a point estimate of the population variance.
Therefore, it can be said that the sample variance, S² is a point estimate for the population variance, b².
Which can also be written as:
b² = S²
b² = S² = 2.42
• The point estimate for the population variance is 2.42
Answer:
Number cube: 1/6 Tossing tails on a coin: 1/2
A number cube is 6 sided, so the probability would be 1/6.
A coin has 2 sides, heads and tails, so tossing tails would be 1/2.
