Question 35 0/5 pts 9 3 19 @ Details Caught warning in the question code: Division by zero on line 14 in file /var/app/current/assess2/ questions/QuestionHtmlGenerator.php(198) : ev A machine fills bottles with 64 ounces of liquid. The quality-control manager determines that the fill levels are normally distributed with a mean of 64 ounces and a standard deviation of 0.42 ounce. He has an engineering recalibration machine in attempt to lower the standard deviation. After recalibration, the quality-control manager randomly selects 19 bottles from the line and determines that the standard deviation is 0.38 ounce. Is there less variability in the filling machine? Use o = 0.1. The null and alternative hypothesis would be: Ho:p = 0.38 Ho: / - 64 Ho: 0 - 0.42 Ho:0 - 0.38 Ho: 0 = 64 H1:p 64 H1:o
