122044 you, then answer the question in a sentence. Suppose that the weight of gala apples can be described by a Normal model with a mean weight of ounces, and a standard deviation of 1 ounce. We abbreviate this N(6.1). Also suppose that the weight ofNavel oranges can be described by a Normal model with a mean weight of 7.5 ounces. and a standard deviation of 1.5 ounces. This is written N (7.5.1.5). 1. How many standard deviations above or below the mean is a gala apple that weighs 7.5 ounces? 2. How many standard deviations above or below the mean is a navel orange that weighs 7 ounces? 3. Which is larger compared to other fruit of its type, a gala apple that weighs 8.5 ounces, or a navel orange that weighs 10 ounces? Think about your answer in terms of standard deviations. 4. Draw a diagram of the Normal model and the use the 68-95-91? rule to estimate what percentage of gala apples weigh between 5 and 7 ounces. Shade in the region that corresponds to the gala apples that weigh between 5 and 7 ounces. 5. Use the normamff feature from the DISTR menu on your graphing calculator to determine what percentage of gala apples weigh between S and 7 ounces and compare to your answer in 4. When using this Feature, normafcdfowerypper. or) gives the proportion of values of' a Normal model between two numbers tower and upper when the mean is p and the standard deviation is a'. 6. Repeat the steps in 4 and 5 for the percentage of navel oranges that weigh less than 4.5 ounces. You should have a diagram and two numbers to compare again. On the calculator step, when you are including the entire le tail as you are here, use 4.3999 for lower. 7. Draw a diagram of the normal model. shade in the appropriate region and use the namafcdf feature from the DISTR menu on your graphing calculator to nd the percentage of navel oranges that weigh more than 9.3 ounces. on 1 E9 Dashboard Calendar To Do Notifications In bor.r
