In a classic study, Shrauger (1972) examined the effect of an audience on performance for two groups of participants: high self-esteem and low self-esteem individuals. The participants in the study were given a problem-solving task with half of the individuals in each group working alone and a half working with an audience. Performance on the problem-solving task was measured for each individual. The results showed that the presence of an audience had little effect on high self-esteem participants but significantly lowered the performance for the low self-esteem participants. a. How many factors does this study have? What are they? b. Describe this study using the notation system that indicates factors and numbers of levels of each factor.

Question 3 Shoprite is a busy center for residents in East Legon and its surrounding community. Assume that 2 customers arrive every 12 minutes and 3 customers are served every 15 minutes and that currently, there is only one cashier. (i).Determine the average waiting time in minutes before service begins. (ii). Advice the management the proportion of the time that a customer has to wait. (B). Management perceives that the waiting time computed in (ii) above is not acceptable and is faced with two options. Management can either employ an assistant for the cashier or open a second cash machine. The former, if implemented, will enable 4 requests to be served every 15 minutes and the assistant will receive a monthly salary of GH₵160. The latter, if implemented will improve the arrival rate to 1 customer every 12 minutes. However, it requires an initial capital outlay of GH₵3000 and the cashier who will operate the cash machine will receive a monthly salary of GH₵250. The shop…
A research group is interested in the relationship between exposure to mold in households after a major hurricane and the onset of acute respiratory illness in children. Suppose an observational study is conducted over 10 years following the natural disaster and the following two-by-two table was created in order to address the relationship between exposure and outcome. Acute Respiratory Illness No Acute Respiratory Illness Total Mold 378 156 534 No Mold 73 260 333 Total 451 416 867 Calculate the incidence of acute respiratory illness in the exposed and unexposed.
