The manager at a clothing factory wants to test if a new machine is producing a particular type of cloth according to the industry specification or not. It is assumed that breaking strength of this type of cloth is normally distributed with mean of 70 and a standard deviation of 5. A sample of 49 pieces of cloth was selected and the breaking strength measured. This is an example of a: O a. One-sample z-test O b. One-sample t-test Oc. One-sample proportion O d. Dependent samples t-test O e. Independent samples t-test
