In the latest batch produced, a technician has noticed a visual defect that may affect the breaking strength of the devices. To investigate, a sample of 8 devices are randomly selected from the batch and the pressure at which they break are recorded as : 6.6, 7.7, 8.0, 6.3, 6.1, 6.3, 6.3, 6.1 these are summarized as having an average breaking strength of 6.68 psi and a standard deviation of s = 0.75 psi. Test, at significance level α = 0.05, whether there is evidence that the average breaking strength of the batch of devices is less than the required breaking strength, by testing the hypotheses: H 0: μ = 5.5 psi H a: μ < 5.5 psi. An estimate of the population mean is . The standard error is . The distribution is (examples: normal / t12 / chisquare4 / F5,6). The test statistic has value TS=…The time it takes to wash the dishes is uniformaly distributed between 8 minutes and 14 minutes.
