A psychologist who needs two groups of students for a learming experiment decides to select a randorn sample of 103 female college students and 82 male college students. Before the experiment, the psychologist administers an IQ test to both groups to determine if there is a significant difference in their mean IQ scores. The population standard deviation for this IQ test is know to be 10 for both female and male populations. If the sample mean IQ score of the 103 female students is 117.7 and the sample mean IQ Score for the 82 male students is 120.5, can the psychologist conclude that there is a significant difference in the mean IQ score of both groups at a = 5%? Let population 1 be female students and population 2 be male students. Note that direction is not specified in this problem, and the population standard deviation is given. See Chapter 13.

Assume that adults have IQ scores that are normally distributed with a mean of u = 105 and a standard deviation o = 20. Find the probability that a randomly selected adult has an IQ between 95 and 115. Click to view page 1 of the table. Click to view_page 2 of the table. ..... The probability that a randomly selected adult has an IQ between 95 and 115 is (Type an integer or decimal rounded to four decimal places as needed.)
Suppose that dieticians recently recommended a 400 calorie-per-meal intake for children of the age of the data set. To see if each group adheres to this guideline, follow the steps to develop and test a statistical hypothesis. Test the claim that each individual groups’ mean is different from 400 calories. For example, for each group, the null hypothesis should be � = 400. Remember that you have two data sets, so you will be completing the process twice, once for the group of children that participated in meal preparation, and once for the group of children that did not participate (You are NOT testing the difference between the two means, e.g. Ho: �1 = �2). Use 95% as a level of significance, and make sure to report all important statistics with your results, including the mean of each group, the standard deviation of each group, the t–statistic, the critical t values, the p-value, etc. For each group, include a normal distribution sketch, highlighting the rejection regions.…

Sara is a big hip-hop music fan. Her friend Matt is a big rap music fan. They each have a huge library of songs in their digital music libraries. They each randomly sample 50 songs from their libraries and record the lengths of the songs selected. The average of the selected hip-hop songs was x1 = 245 seconds with a sample standard deviation of 4 seconds. The average of the selected rap songs was x2 = 275 seconds with a sample standard deviation of 6 seconds. They would like to know if the average length of hip-hop songs is different than the average length of rap songs. (a) What are the appropriate null and alternative hypotheses for this test?

Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The Bombardier Dash 8 aircraft can carry 37 passengers, and a flight has fuel and baggage that allows for a total passenger load of 6200 lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the passengers is greater than 6200lb/37 = 167.6lb. What is the probability that the aircraft is overloaded? Should the pilot take any action to correct for an overloaded aircraft? Assume that weights of men are normally distributed with a mean of 185.47 lb and a standard deviation of 39 lb. draw probability density function
