Question 4 (3+3 marks) al Wires manufactured for a certain computer system are specified to have a resistance of between 0.1 1 and 0.16 ohm The actual measured resistances of the wires produced by Company A have a normal probability distribution, with a mean of 0.14 ohms, and a standard deviation of 0.903 ohms. What is the probability that a randomly selected wire from Company A's production lot will meet the specifications? by The recommended dietary allowance (RDA) of iron for adult females under the age of 51 is 18 milligrams (mg) per day. The following iron intakes, in milligrams, were obtained during a 24-hour period for 45 randomly selected adult females under the age of 51. 150 141 14.4 14.6 10.9 18.1 18.2 183 15.0 16.0 12.6 16.6 20.7 19.8 11.6 12.8 15.6 110 15.3 9.4 19.5 145 16.6 11.5 16.4 12:5 14.6 11.9 125 18.6. 13.1 121 10.7 17.3 12.4 17.0 63 16.8 125 163 14.7 12.7 163 115 At the 14% significance level, do the data suggest that adult females under the age of 51 are, on average, getting less than the RDA of 18 my of iron? Assume that the population standard deviation is 4.3 ing
