The mean birth weight of infants in the United States is μ = 3315 grams. Let X be the birth weight (in grams) of a randomly selected infant in Jerusalem. Assume that the distribution of X is N(μ, σ2), where μ and σ2 are unknown. 25 new-born infants randomly selected in Jerusalem yielded a sample mean of 3515 grams and a standard deviation of s = 500 grams. Use the data to test the null hypothesis H0: μ = 3315...
