Question

Workers at a certain soda drink factory collected data on the volumes (in cances) of a simple random sample of 16 cans of the soda drink. These volumes have a mean of 12.19QZ and a standard deviation of 0.14QZ, and they appear to be from a normally distributed population. If the workers want the filling process to work so that almost all cans have volumes between 11.95QZ and 12.59 QZ, the range rule of thumb can be used to estimate that the standard deviation should be less than 01.16QZ. Use the sample data to test the claim that the population of volumes has a standard deviation less than 0.16QZ. Use a 0.025 significance level. Complets parts through below. Identify the null and alternative hypothesis. Choose the correct answer below. H_0:sihma=0.16QZ H_1:sigma lt 0.16QZ H_0:sigma=0.16QZ H_1:sigmaneq0.16QZ H_0:sigma gt 0.16QZ H_1:sigma=0.16QZ H_0:sigmagreaterthanorequalto0.16QZ H_1:sigmalt0.16QZ

Explanation / Answer

Ho : sigma = 16

Ha :; sigma < 16

because you want to see if the standard deviation is less tha n 16
