Hi, I need help. Thank you.

The graph illustrates a normal distribution for the prices paid for a particular model of HD television. The mean price paid is $1400 and the standard deviation is S80. Round answers to at least 4 decimal places, use technology. 1160 1240 1320 1400 1480 1560 1640 Distribution of Prices What is the probability that a buyer paid between S1320 and $1480? What is the probability that a buyer paid between 51240 and 51400? What price would the buyer pay to get 6% the most expensive HD televisions? Assume that the readings at freezing on a bundle of thermometers are normally distributed with a mean of O'C and a standard deviation of I .00'C. A single thermometer is randomly selected and tested. Find the probability of obtaining a reading greater than 2.1650C. Leave your answer as a decimal value rounded to 4 decimal places. > 2.165) Keke's Kookies (https://kekekookies.com/) sells mini cookies in packs of 5 and has determined a probability distribution for the number of cookies that they sell in a given day. 10 15 20 a.
