A well-designed and safe workplace can contribute greatly to increasing productivity. It is especially important that workers not be asked to perform tasks, such as lifting, that exceed their capabilities. The following data on maximum weight of lift (MWOL, in kilograms) for a frequency of 4 lifts per minute were reported in a certain article:

28.3 39.1 28.8 24.3 29.7

Suppose that it is reasonable to regard the sample as a random sample from the population of healthy males, age 18-30. Do the data suggest that the population mean MWOL exceeds 27.5? Carry out a test of the relevant hypotheses using a .05 significance level.

Reject H0 OR Fail to reject H0

Reasons why productivity is important are numerous. Although productivity increases can have a negative impact in an economic situation where the productivity increases at a faster rate than the growth of the economy, generally, productivity increases typically have a positive impact. Simply, productivity is an important competitive issue. It can be important and reviewed on three levels: national, organizational, and personal.

The pH level of soil can be very important toward plant growth, especially for blueberries which require acidic soil. Suppose the population distribution of soil pH levels in our area is normally distributed with a population mean pH level of 5.5 and a population standard deviation of 0.1. a.) Suppose you select a random sample of size n=1 from your backyard and test the soil. What is the probability of selecting soil with a pH less than 5.46? b.) Suppose...
