The mean weight of chihuahuas at a local pet shelter is 6.6 pounds. a sample of seven chihuahuas is randomly selected and their weights are recorded as 9.0, 7.3, 6.0, 8.8, 6.8, 8.4, and 6.6 pounds. the null hypothesis is
A null hypothesis is a kind of hypothesis used in statistics. It proposes that, in a set of given observations, no statistical significance exists
The null hypothesis attempts to show that no variation exists between variables or that a single variable is no different than its mean.
It is presumed to be true until statistical evidence nullifies it for an alternative hypothesis. So, for this problem, the null hypothesis is: [tex]H_{0}:\mu=6.6 pounds[/tex]
