- A survey found that women's heights are normally distributed with mean 62.2 in, and standard deviation 2.7 in. The survey also found that men's heights are normally distributed with a mean 69.1 in. and standard deviation 29. Complete pas a through c below. a. Most of the live characters at an amusement park have height requirements with a minimum of 4 ft 9 in. and a maximum of 6 ft 3 in. Find the percentage of women meeting the height equrement The percentage of women who meet the height requirement is %. (Round to two decimal places as needed.) b. Find the percentage of men meeting the height requirement. The percentage of men who meet the height requirement is %, (Round to two decimal places as needed.) c. If the height requirements are changed to exclude only the tallest 5% of men and the shortest 5% of women what are the new height regurements The new height requirements are at least in. and at most in. (Round to one decimal place as needed.)A set of data items is normally distributed with a mean of 50 and a standard deviation of 8. Convert 50 to a z-score. 250 (Do not round until the final answer. Then round to the nearest hundredth as needed.) line ces urcesThermometers used at the Tongas National Park in Alaska are supposed to give readings of 0° C at the freezing point of water. However, not all thermometers do, some give readings below 0°C (denoted by negative numbers) and some give readings above 0° C (denoted by positive numbers). Assume that the mean reading is 0° C and the standard deviation is 1.00° C. Also assume that these readings are normally distributed. A thermometer is randomly selected and tested. If 2% of the thermometers are rejected because they have readings that are too high (but all other thermometers are acceptable), find the the temperature that separates the rejected thermometers from the others. Round your answer to two decimal places. Temperature = Shade the appropriate region be sure to round you previous answer to one decimal place in order to graph: Shade: Left of a value Click and drag the arrows to adjust the values. -3 1 -/ 2 -1.5

Assume the population is normally distrib a standard deviation of 15 months. Find the probabil he mean age of a cample o of 26 ulThe kelvin is a unit of measurement for temperature; 0 K is absolute zero, the temperature at which all thermal motion ceases. Conversion from Fahrenheit to Kelvin is given by K=× (F-32)+273. The average daily temperature in Monrovia, Liberia, is 78.35°F with a standard deviation of 6.3°F. If a scientist converts Monrovia daily temperatures to the Kelvin scale, what will be the new mean and standard deviation?
