Chi - square According to genetics theory (e.g. Mancuso, et al. 2009; doi:10.1038/nature08401), red-green colour blindness in humans is a recessive gender-linked characteristic. Theory shows that 50% of children have normal vision and are not carriers of the colour blindness gene, whilst 25% of children have normal vision and are carriers of the colour blindness gene, and 25% of children are red-green colourblind and are carriers of the colour blindness gene. A random sample of 200 children was taken with the following results: *view table down below* a) use descriptive statistics to represent the data b) test at the 1% level of significance, if the sample follows genetics theory
Quality Control: A company has four photocopy machines A, B, C and D. The probability that a given machine will break down on a particular day is P(A) = %50 P(B) = 15 P(C) = 1⁹/100 P(D) = 11/100 Assuming independence, what is the probability on a particular day that all machines will break down?

Question: Probability, Bayes’ Theorem: A Covid-19 test produces false negatives 2% of the time and false positive 5% of the time. 10% of a city has the virus. Answer the following questions: If a person test negative, what is the probability that the person carries the virus? What is the probability that a person carrying the virus tests negative three times in a row through independent tests? What is the probability that someone who tests negative twice in a row of independent tests is a healthy person? Considering that the test has low false negative and false positive rates, please reflect on the results you obtained in parts (i) and (ii).
