A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 414 gram setting. It is believed that the machine is underfilling the bags. A 8 bag sample had a mean of 407 grams with a standard deviation of 18. A level of significance of 0.025 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
Reject H0 if t <:__________
Solutions
Expert Solution
We have here,
Left tailed t test.
Sample size = n = 8
Degree of freedom =n-1=8-1=7
| Reject H0 if t < -2.365 |
