Question

The correct conclusion is that we conclude that the average length of stay of all surgeries of this type days.

What level of concern do you have for the validity of your results?

Low our sample size is near 30, so while that's likely sufficient for to be approximately normally distributed, seeing that the original data isn't extremely skewed would make us feel more comfortable

Moderate
the original data is not normally distributed which is an assumptions violation

Extreme
we should not use any part of what we've done to make a conclusion

None
our sample size is larger than 30 so there should be no problem with the conclusion

Determine the critical values.
O +2.023
O +2.024
O+1.685
O +2.026
O +1.687

O Fail to reject Ho
O Reject Ho

A health professional obtains records for 38 patients who have undergone a certain
surgical procedure and finds the average length of stay is 3.73 days with a standard
deviation of 1.44 days. Using a = 0.05, is there evidence to suggest the actual average
length of stay for this surgical procedure is 3 days?
What are the hypotheses?
O Ho: x= 3.73 vs H₁ : 3.73
☎ ‡
Ο Ηo : μ
= 3.73 vs H₁ : µ ‡ 3.73
O Ho: = 3 vs H₁ : x ‡ 3
Hoμ = 3 vs H₁ : µ ‡ 3
Calculate the test statistic using the correct letter.
Oz = 3.13
Ot=-3.13
Ot = 3.13
Oz = -3.13

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
