Type the correct answer in each box. Sam The graph shows the normal distribution of the length of similar components produced by a company with a mean of 5 centimeters and a standard deviation of 0.02 centimeters. Ifa component is chosen at random, the probability that the length of this component is between 4.98 centimeters and 5.02 centimeters is about % and the probability that the length of this component is between 5.02 centimeters and 5.04 centimeters is about 9h. Identify each example as a discrete random variable or a continuous random variable. the average annual increase a car's speed at different times in fuel price the number of cars passing the number of phone calls made through a toll both in an hour in a day the salaries of employees in an office Discrete Random Variable Continuous Random VariableA sociologist wants to know the opinions of employed adult women about government funding for day care. The women were asked to rate the government support on a scale of 1 to 5, with a score of 1 representing the least support and a score of 5 representing the highest support. The probability distribution chart is given. Rating 1 too little | 2 helpful but not enough | 3 make a difference but insufficent |4 sufficent | 5 generous Probablety 0.110 0.206 0.464 0.201 0.119 What percentage of women think that the support is sufficient?
