In their advertisements, the manufacturers of a diet pill claims that taken daily, their pill will produce an average weight loss of 10 pounds in one month, with standard deviation 3 pounds. In order to determine if this is a valid claim, an independent testing agency selects 36 people to take the pill daily for a month and found the mean weight loss for this group was 9 pounds.
Does this indicate at a 5% level that the mean weight loss is less than 10 pounds?
What are the null and alternative hypotheses?
Select one:
a. H0: μ = 10 and HA: μ < 10
b. H0: μ = 0.05 and HA: μ < 0.05
c. H0: μ = 10 and HA: μ > 10
d. H0: μ = 10 and HA: μ = 9

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
