In a sample of 103 bags of dog food, the average weight was found to be 21.5 lb with a standard deviation of 0.5 lb.

Give a point estimate for the population variance of the weight of the bags of dog food.

Round your answer to two decimal places, if necessary.

The point estimate for the population variance of the weight of the bags of dog food is calculated by squaring the sample standard deviation. In this case, the variance is 0.25lb².

Explanation:

To calculate the point estimate for population variance, we rely on the given sample standard deviation. The squared standard deviation is the variance. In this particular instance, the sample standard deviation is 0.5lb. So therefore, we calculate the variance by squaring the sample standard deviation: 0.5lb * 0.5lb = 0.25lb². This serves as our point estimate for the population variance of the weight of the bags of dog food.
