Weights of 5 randomly chosen new-born babies were (in kg): 3.75, 3.45, 3.50, 3.90, 3.25. Find 90% confidence interval for the mean of the weight of new-born babies.

In a study on newborn health, a hospital records the weights of 100 randomly selected newborns. The average weight is found to be 3.5 kg with a standard deviation of 0.5 kg. Find an 80% confidence interval for the average weight of newborns in this hospital.

If the weights of newborn babies follows Normal distribution. A sample of 50 newborn babies have average weight of 3.09 Kg and sample standard deviation 0.7569 Kg. Then; 95% confidence interval of the weights is (2.7605,3.4195) (2.8749,3.3050) None (2.8428,3.3372) (2.8033,3.3766)

Exercise 2. Weights of 5 randomly chosen new-born babies were (in kg): 3,75 3,45 3,50 3,90 3, 25. Assuming normal distribution for the weight, find 99 % confidence interval for the average weight of a new-born baby. Exercise 4. Knowing that 99% confidence interval was [5,02, 6,98] and assuming normal distribution of the examined feature, find the value of a sample mean?
