Question

Suppose that the weights (in pounds) of newborn babies were approximately normal with mean 6.9 pounds and standard deviation of 0.57 pounds. Suppose a simple random sample of 50 newborn babies is taken. The sampling distribution of the mean is approximately because n ? 30. To calculate any probability, we first need to find ?x? and ?x?. Round your answers to the nearest three decimal places, when applicable. Don't include units. ?x? = ?x? = Find the probability that the mean weight of these 50 newborn babies is 7 pounds or higher:

Suppose that the weights (in pounds) of newborn babies were approximately normal with mean 6.9 pounds and standard deviation of 0.57 pounds. Suppose a simple random sample of 50 newborn babies is taken. The sampling distribution of the mean is approximately because n ≥ 30. To calculate any probability, we first need to find μx̄ and σx̄. Round your answers to the nearest three decimal places, when applicable. Don't include units. μx̄ = σx̄ = Find the probability that the mean weight of these 50 newborn babies is 7 pounds or higher:
