A company makes high-definition televisions and does not like to have defective pixels. Historically,the mean number of defective pixels in a TV is 20. An engineer is hired to make better TV’s that havefewer defective pixels. After his first week of work he claims that he can significantly improve the currentmethod. To check his claim you try his new method on 100 new televisions. The average number ofdefective pixels in those 100 TV’s is 19.1. Assume that the new method doesn’t change the standarddeviation of defective pixels, which has always been 4.(a) Test if the new method is significantly better than the old one at the α = 0.05 level.(b) Using the new method, assume that the mean number of defective pixels is actually 19. What is thechance that your test from part 1 will conclude that the new method is statistically more effective?

Over the past several years, the proportion of one-person households has been increasing. The Census Bureau would like to test the hypothesis that the proportion of one-person exceeds 0.27. A random sample of 125 households found that 43 consisted of one person. The census bureau would like to set a = 0.05. Use the p-value approach to test this hypothesis. Explain.
Pls help ASAP
please give some detailed solution and please do not copy other's work,thanks!! According to a union agreement, the mean income for all senior-level assembly-line workers in a large company is $500 per week. A representative of a women's group decides to analyse whether the mean income for female employees matches this norm. For a random sample of 50 female employees, the mean is $410 and the SD is $90. Test with a-0.05, whether the mean income of female employees differs from $500 per week. What is the probability of the Type II error in this case?
Hi, I am having trouble finding the P-value for this problem. Could you please explain step by step how will I figure out the P-value? Thanks.
what happens to the sample mean when sample size decrease? decrease stay the same increase cannot be predictable
please help! rate will be given. write the complete solutions and legibly. APPLIED STATISTICS AND PROBABILITY FOR ENGINEERS > CORRELATION In an article in IEEE Transactions on Instrumentation and Measurement (2001, Vol. 50, pp. 986–990), researchers reported on a study of the effects of reducing current draw in a magnetic core by electronic means. They measured the current in a magnetic winding with and without the electronics in a paired experiment. Data for the case without electronics are provided inthe following table. See the attached photo Answer the following: a. Graph the data and fit a regression line to predict current without electronics to supply voltage. Is there a significant regression at α = 0.05? What is the P-value?b. Estimate the correlation coefficient.c. Test the hypothesis that ρ = 0 against the alternative ρ ≠ 0 with α = 0.05. What is the P-value?d. Compute a 95% confidence interval for the correlation coefficient.
The number of needed repairs while under warranty for a Sure Cut lawnmower has a population distribution as shown in the probability histogram below. The population mean is also given. Population 0.6 - 0.5- 0.4- population mean: u=1.15 0.3- 0.2- Number of repairs Probability
Scatter can be summarized using the standard error of estimate?
A survey was conducted to measure the height of Canadian men. In the survey, respondents were grouped by age. In the 20-29 age group, the height was normally distributed, with a mean of 69.2 inches and a standard deviation of 2.9 inches. A study participant is randomly selected. Find P80, the 80th percentile Find P50, the 50th percentile Find the height that corresponds to the first quartile please show all steps using excel formulas
