Using the sample random sample of weight of women from a data set, we obtain these sample statistics; n=35 and x= 145.03lb. Research from other sources suggest that the population of weights of women has a standard deviation given by o= 31.471b
a) Find the best point estimate of the mean weight
of all women.
b) Find a 99% confidence interval estimate of the
mean weight of all women.

Question

Using the sample random sample of weight of women from a data set, we obtain these sample statistics; n=35 and x= 145.03lb. Research from other sources suggest that the population of weights of women has a standard deviation given by o= 31.471b
a) Find the best point estimate of the mean weight 
of all women.
b) Find a 99% confidence interval estimate of the
mean weight of all women.
