Question

. For the variable Jength of hospital stay." determine the sampling distribution of the sample mean for samples al 70 patients The sampling distribution wir be approximately normal whth mean μ and standard deviation σ ∗ =07369 days. (Round to four decimal places as nooded)

Answer 1

The sampling distribution of the sample mean for samples of 70 patients can be approximated as a normal distribution with a mean of 0 and a standard deviation of 0.00879 days.

Step-by-step explanation:

The sampling distribution of the sample mean for samples of 70 patients with a standard deviation of σ ∗ = 0.07369 days can be approximated as a normal distribution with a mean of μ and a standard deviation of σ/√n. In this case, the mean is μ = 0 and the standard deviation is σ/√n = 0.07369/√70 ≈ 0.00879 days.
