You are estimating the mean waiting time in line at a particular fast-foodrestaurant. You ask 30 customers, at varying times of the day. How longthey waited in line before placing their order. You then take the average ofthese values and use this average to estimate the mean waiting time forall customers. The average of the 30 values is an example of a(n):Confidence estimateChebyshev estimatePoint estimateWhen n≥30 and the population standard deviation is unknown, what isthe appropriate distribution?PRОтO ZO Interval estimate We use the t-distribution to make a confidence interval for the population *mean from which the sample is drawn is normally distributed, thepopulation standard deviation is unknown, and the sample size is at least:251530

Suppose a professor uses a normal distribution to assign grades in her math class. • She assigns an A to students scoring more than 1.9 standard deviations above the mean. • She assigns an F to students scoring more than 2.2 standard deviations below the mean. She assigns a B to students who Score between 1 and 1.9 standard deviations above the mean. • She assigns a D to students who Score between 1.2 and 2.2 standard deviations below the mean. • All other students get a C. Use the Cumulative Z-Score Table to answer the following questions. The Z-Score Table can be found below by selecting "Read". Write your answer as a percent using 2 decimal places. What percent of the class receives each grade assuming the scores are normally distributed? Hint % will recieve an A % will recieve a B % will recieve a C % will recieve a D % will recieve an F

Many people like to play app based games on their mobile devices. Suppose we would like to estimate the average amount of time (in hours) per week students have played an app-based game on their mobile device at CSU Stan. In order to do this, we take a random sample of 20 students and ask them how many hours they have played an app- based game in the last week. The following data were collected: 11 4 5.5 5.5 7 6.2 10 10 7.5 6 7 7.5 2.5 Which of the following is the correct 99% confidence interval for the estimate of the average number of hours (per week) that all CSU Stan students have played an app- based game? [5.28, 7.59] [4.86, 8.01] [5.48,7.39] [5.86, 7.01]
