A population has a mean of u=30 and a standard deviation of sd=5. a. If 5 points were added to every score in the population, what would be the new values for the mean and standard deviation? b. If every score in the population were multiplied by 3, what would be the new values for the mean and standard deviation?
The mean average of the numbers a, b, 8, 5, and 10 is 6, and the variance is 6.80. What set of the given numbers a and b that agree to the given mean average value and the variance of the population?
i: a=0, b=7 ii: a=5, b=2, iii. a=1, b=6, iv. a=3, b=4
Subject: Applied Statistics
Suppose you have purchased a filling machine for candy bags that is supposed to fill each bag with 16 oz of candy. Assume that the weights of filled bags are approximately normally distributed. A random sample of 10 bags yields the following data (in oz):
15.87 16.02 15.78 15.83 15.69 15.81 16.04 15.81 15.92 16.10
On the basis of these data, can you conclude that the mean fill weight is actually less than 16 oz?
State the appropriate null and alternate hypotheses.
Compute the value of the test statistic.
Find the P-value and state your conclusion.
