Suppose a batch of metal shafts produced in a manufacturing company have a variance of 1 and a mean diameter of 212 inches. If 75 shafts are sampled at random from the batch, what is the probability that the mean diameter of the sample shafts would be less than 212.3 inches

City l has a temperature of −3 °f. city m has a temperature of −7 °f. use the number line shown to answer the questions: number line from negative 8 to positive 8 in increments of 1 is shown. part a: write an inequality to compare the temperatures of the two cities. (3 points) part b: explain what the inequality means in relation to the positions of these numbers on the number line. (4 points) part c: use the number line to explain which city is warmer. (3 points)
