Please show clear and complete solution. Last 30 minutes thank you! Question 4Two different types of polishing solutions are being evaluated for possible use in tumble-polishoperation for manufacturing interocular lenses used in the human eye following cataract surgery.Three hundred lenses were tumble polished using the first polishing solution, and of this number,253 had no polishing-induced defects. Another 300 lenses were tumble-polished using thesecond polishing solution, and 196 lenses were satisfactory upon completion.Is there any reason to believe that the two polishing solutions differ? Use a = 0.01.O a. Reject the Null hypothesis. 5.36 > 1.65O b. Reject the Null hypothesis. 5.36 > 1.96O c. All of the choicesO d. Reject the Null hypothesis. 5.36 > 2.58

Two different types of polishing solutions are being evaluated for possible use in a tumble-polish operation for manufacturing interocular lenses used in the human eye following cataract surgery. Three hundred lenses were tumble polished using the first polishing solution, and ofthis number, 253 had no polishing-induced defects. Another 300 lenses were tumble-polishedusing the second polishing solution, and 196 lenses were satisfactory upon completion.(a) Is there any reason to believe that the two polishing solutions differ?

QUESTION 1 The Ministry of Health and Social Services (MoHSS) in Namibia intends to embark upon a COVID19 vaccination campaign in the Country. But before deciding which type of COVID19 vaccine to be ordered from the Manufacturers, they first carried out a survey on some countries around the world in order to establish the most preferred vaccine. The findings revealed that: Sixty-eight (68) of them prefer the Pfizer; fifty-two (52) prefer the Moderna; and forty-eight (48) prefer the AstraZeneca. Thirty-six (36) of them prefer Pfizer and AstraZeneca; twenty-two (22) of them prefer Moderna and AstraZeneca; None of the countries prefer AstraZeneca only; 24 prefer Moderna only; 26 prefer Pfizer only; and the remaining 90 countries preferred none of the vaccines. REQUIRED: A.)How many preferred Pfizer or AstraZeneca but not Moderna? B.)What is the ratio (in the simplest form) of the countries that preferred Moderna to those that prefer Pfizer and AstraZeneca? C.)How many countries did not…

Question 4a. A large accountancy firm finds that over the long run 10% of its statements for clients are in error in some way. A quality assurance officer at the firm investigating the source of the errors takes a sample of 20 statements produced by a single employee and classifies each as being “in error” or “not in error”.i. If the variable X is used to represent the number of statements in the sample that are in error, and assuming the error rate is the firm’s level of 10% then state:• the type of distribution this variable has; and• the parameter/s of this distribution. ii. Determine the probability that 2 or less returns in this sample are in error. The quality assurance officer found that there were 5 statements in the sample that were in error.iii. Determine the probability of finding 5 or more returns in error if indeed the error rate was 10%. iv. Based upon your answer for part iii., what conclusion might the quality assurance office make about this employee in terms of the…

Resistors labeled as 100 Ω are purchased from two different vendors. The specification for this type of resistor is that its actual resistance be within 5% of its labeled resistance. In a sample of 180 resistors from vendor A, 150 of them met the specification. In a sample of 270 resistors purchased from vendor B, 233 of them met the specification. Vendor A is the current supplier, but if the data demonstrate convincingly that a greater proportion of the resistors from vendor B meet the specification, a change will be made. a) State the appropriate null and alternate hypotheses. b) Find the P-value. c) Should a change be made?
Resistors labeled as 100 Ω are purchased from two different vendors. The specification for this type of resistor is that its actual resistance be within 5% of its labeled resistance. In a sample of 180 resistors from vendor A, 149 of them met the specification. In a sample of 270 resistors purchased from vendor B, 233 of them met the specification. Vendor A is the current supplier, but if the data demonstrate convincingly that a greater proportion of the resistors from vendor B meet the specification, a change will be made. P-value?
