Question

Data originally from DASL http://lib.stat.cmu.edu/DASL/Datafiles/CancerSurvival.html (Links to an external site.).

Some bronchial cancer patients had the following survival times (in days) after receiving a certain treatment: 20, 37, 63, 64, 72, 81, 138, 151, 155, 166, 166, 223, 245, 246, 450, 459. (The second instance of “166” is not a mistake.)

Do these numbers suggest that the average survival time, for all bronchial cancer patients who receive that treatment, is significantly different from 200 days?

CANCER SURVIVAL

Report an appropriate one-sample hypothesis test and use a 10% significance level.

For Step 4 of the six-step process that was taught in this class, choose the BEST option to complete the following sentence:

We assume that the sample of subjects is a SRS and we assume that the population of observations has no outliers ...

and is Normally distributed.

and is without a doubt bell-shaped.

and is Uniformly distributed.

(nothing needs to go here because the sample size is large).

and is skewed.

and is symmetric.

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.
