Det The population of weights of a particular fruit is normally distributed, with a mean of 554 grams and a standard deviation of 14 grams. If 2 fruits are picked at random, then 20% of the time, their mean weigh will be greater than how many grams? Round your answer to the nearest gram.

The Shake Out Earthquake Scenario is based on a magnitude 7.8 earthquake and serve as the basis for California's annual Great Shake Out Drill. In the context of the magnitudes considered here, is that magnitude significantly high or significantly low? Explain and show how you came to your conclusion.

Assume that thermometer readings are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A thermometer is randomly selected and tested. For the case below, draw a sketch, and find the probability of the reading. (The given values are in Celsius degrees.) Between 1.50 and 2.25 Click to view page 1 of the table. Click to view page 2 of the table. Draw a sketch. Choose the correct graph below. O A. A z=1.50 Z=2.25 The probability of getting a reading between 1.50°C and 2.25°C is (Round to four decimal places as needed.) O B. Z=1.50 Z=2.25 Ly O C. z=1.50 z=2.25
