QUESTION 4 Titus Company, a recycling computer company ordered computer components from two differentsuppliers, namely Supplier A and Supplier B. Since Covid-19 outbreak in Malaysia, the companyhas financial constraint and need to identify which supplier has more reliable component. Duringassembly process, the number of defective components is recorded. The number of defectivecomponents for each supplier from 12 random days in a month is given in Table 3. Assume thatthe data are normally distributed and the two population standard deviations are not equal.Table 3Day 1 2 3 4 5 6 7 8 9 10 11 12Supplier A 34 36 40 39 30 38 37 39 35 41 40 38Supplier B 40 40 38 39 37 35 42 41 40 41 33 39(i) Construct a 90% confidence interval for the difference in the true average number of defectivecomponents between both suppliers.(ii) Interpret the parameter estimate obtained in (i)?(iii) What is the effect on…
A low-level CDC bureaucrat wants to please his boss by gathering evidence thatthe current government-mandated shutdown of society is not causing people’s mentalhealth to deteriorate, so that it can safely be continued for several years if anyexpert says it’s necessary.He polls a random sample of 1600 citizens, gathering data on such items asincome loss, weight gain, access to toilet paper, hours spent binge-watchingNetflix, and number of injuries caused by household fights, and compiles all thisinto a scientifically-weighted “misery index”.The mean misery index from the sample is 99.2; it seems reasonable to use apopulation standard deviation σ = 19.1.a) Does this information provide significant evidence (at the 5% level) that thenationwide mean misery index is less than 100? Set up appropriate null andalternative hypotheses, calculate the appropriate test statistic, find the P-value,and state your conclusion.

Delmarva Power is a utility company that would like to predict the monthly heating bill for a household in Kent County during the month of January. A random sample of 18 households in the county were selected and their January heating bill recorded. This data is shown in the table below along with square footage of the house (SF), the age of the heating system in years (Age,) and the type of heating system (heat pump =1 or natural gas = 2).

This problem is based on information taken from The Merck Manual (a reference manual used in most medical and nursing schools). Diltiazem is a commonly prescribed drug for hypertension. However, diltiazem causes headaches in about 12% of patients using the drug. It is hypothesized that regular exercise might help reduce the headaches. If a random sample of 205 patients using diltiazem exercised regularly and only 18 had headaches, would this indicate a reduction in the population proportion of patients having headaches? Use a 1% level of significance. A-What is the value of the sample test statistic? (Round your answers to two decimal places.) B- Find the P-value of the test statistic. (Round your answers to four decimal places.)

Question 6A multinational corporation is conducting a study to see how its employees in five different countries respond to three gifts in an incentivescheme. The numbers of employees who choose each of the three gifts(G1 to G3) in each of the five countries (A to E) are given in the tablein ‘Dataset6’ in the Excel document.1. Set up the structure of an appropriate statistical test to determine whether the data supports a link between choice of gift andcountry, including the statistic to be used.2.

In Colorado, there is a large group of deer that spend their summer months in a region on one side of a highway and survive the winter months in a lower region on the other side. To determine if the highway has disturbed deer migration to the winter feeding area, the following data were gathered on a random sample of 10 wilderness districts in the winter feeding area. Row B represents the average January deer count for a 5-year period before the highway was built, and row A represents the average January deer count for a 5-year period after the highway was built. The highway department claims that the January population has not changed. Test this claim against the claim that the January population has dropped. Use a 5% level of significance. Units used in the table are hundreds of deer. (Let d = B − A.)
