A company manufacturing computer chips finds that 5% of all chips manufactured are defective. Management is concerned that employee inattention is partially responsible for the high defect rate. In an effort to decrease the percentage of defective chips, management decides to offer incentives to employees who have lower defect rates on their shifts. The incentive program is instituted for one month. If successful, the company will continue with the incentive program. a. Write the company's null and alternative hypotheses. Make sure to include the correct parameter, sign and number.Ho:   H1:   b. In this context describe a Type I error and the impact such an error would have on the company. Management thinks the incentive program was effective, when in fact it did not lower the defective rate from 5%. Management thinks the incentive program did not work, when in fact it did lower the defective rate from 5%. c. In this context describe a Type II error and the impact such an error…

The t-test on individual model coefficients is a test on the significance of the coefficient of apredictor as if it were the last variable added to a model that already contains all the otherpredictors. (true or false?)
When is a researcher at risk of making a Type II error? Group of answer choices: whenever H0 is rejected whenever H1 is rejected whenever H0 fails to be rejected The risk of a Type II error is independent of the decision from a hypothesis test.
The average drying time of a manufacturer’s paint is 20 minutes. Investigating the effectiveness of a modifica-tion in the chemical composition of her paint, the manu-facturer wants to test the null hypothesis μ = 20 minutes against a suitable alternative, where μ is the average dry-ing time of the modified paint. (a) What alternative hypothesis should the manufactureruse if she does not want to make the modification in thechemical composition of the paint unless it decreases thedrying time?(b) What alternative hypothesis should the manufactureruse if the new process is actually cheaper and she wants tomake the modification unless it increases the drying timeof the paint?
The relationship between the independent variable (IV) and the dependent variable (DV) is likely to be mediated by a third variable (MV). With regard to the statement above, which of the following is most likely to be correct? A IV = Students’ performance (i.e., marks) in the formative assessment; DV = Students’ performance (i.e., marks) in the summative assessment, and MV = Students’ level of comfort with the venue of the assessments B IV = Students’ performance (i.e., marks) in the summative assessment; DV = Students’ performance (i.e., marks) in the formative assessment, and MV = Students’ level of preparation for the assessments. C IV = Students’ performance (i.e., marks) in the formative assessment; DV = Students’ performance (i.e., marks) in the summative assessment, and MV = Students’ level of preparation for the assessments D IV = Students’ performance (i.e., marks) in the summative assessment; DV = Students’ performance (i.e., marks) in the formative assessment,…
In terms of the model parameters, state the null hypothesis that, after controlling for sales and roe, ros has no effect on CEO salary. State the alternative that better stock market performance increases a CEO’s salary.
Q) Create a conceptual model and also develop null and alternate hypotheses of the following. The labor force heterogeneity enhances more to organizational effectiveness because each group brings its own special expertise and skills to the workplace. Collaboration can be leveraged, however, only if managers know how to tackle the special talents of the different working group; otherwise, they will remain unexploited.
Which is the correct null hypothesis based on this statement: People with diabetes have higher systolic blood pressure than people without diabetes? People with diabetes have lower systolic blood pressure than people without diabetes. People with diabetes have equal systolic blood pressure when compared to people without diabetes. People with diabetes have a systolic blood pressure equal to or lower than people without diabetes. None of these are a null hypothesis.
A local chess club claims that the length of time to play a game has a mean of 43 minutes or more. Write sentences describing type I and type II errors for a hypothesis test of this claim.

An urban community wants to show that the incidence of breast cancer is higher in their locality than in a neighboring rural area. (PCB levels were found to be higher in the soil of the urban community). If you find that in the urban community 20 out of 200 adult women have breast cancer and that in the rural community 10 out of 150 adult women have it, could you conclude, at a significance level of 0.05, that breast cancer is more prevalent in the urban community?1. The parameter of interest is:2. The hypotheses for this test are:3. The calculated test statistic is:4. The critical region is:5. Draw the critical region (make decision):6. It can be concluded that:
