A machine is designed to fill jars with 16 ounces of coffee. A consumer suspects that the machine is not filling the jars completely. A sample of 8 jars has a mean of 15.6 ounces and a standard deviation of 0.3 ounce. Is there enough evidence to support the consumer's conjecture at alpha = 0.05? Second, calculate the critical value and degrees of freedom.

  • statistics - ,

    Yes there is enough evidence to support----
    T = (16-15.6)/(.3/sqrt(8))
    df = n-1
    df = 8-1 = 7

    critical t value = 1.895
