3. The weights of a random sample of containers that are supposed to weigh 100 grams are listed below. 27 marks 105.2 103.5 98.6 100.3 99.1 97.8 101.2 96.0 The sample statistics are: x = 100.213, s = 3.025 Can we infer, at the 5% significance level, that the variance of container weights is greater than 7? Assume the required conditions are satisfied. Ho : H1 : Conclusion: Reject Ho Do not reject Ho Reason for conclusion
