- you should calculate the required probabilities using tables A model for normal human body temperature, X, when measured orally in F, is that it is normally distributed, X N(98.2, 0.5184). According to the model, what proportion of people have a normal body temperature of 99 F or more? (0) (i) Find the normal body temperature such that, according to the model, only 10% of people have a lower normal body temperature. (ii) Let W denote normal human body temperature, when measured orally in C. Given that W =59 (X-32) and X N(98.2, 0.5184), what is the distribution of W?Please do not give solution in image formate thanku.On a test of spatial reasoning, it is found that scores for men follow a normal distribution with mean mu = 200 and standard deviation sigma = 60 Scores for women also follow a normal distribution, but with mu = 180 and sigma = 20 What percentage of men's scores fall between 200 and 305 in the distribution (Round your answer to 2 decimal places .
