Q2. A laundry for car wash found that the average, for small size car, cleaning time is 5mins in the morning and 6.5 mins at evening time when a sample of size 30 is taken at the twotime periods. From the previous record, the laundry manager knew that car oj = 2 mins for themorning shift and oz = 2.5 mins for morning and evening repectively. Find the interval estimatefor 4 - 42 with 90% confidence level.

The confidence interval is the combined value of margin of error and the sample statistic. Where…

In a survey, the sample consisted of 1087 adults who were parents of school-aged children. The sample was selected in a way that makes it reasonable to regard it as representative of the population of parents of school-aged children. One question on the survey asked respondents how much time (in hours) per month they spent volunteering at their children's school during the previous school year. The following summary statistics for time volunteered per month are given below. n = 1087 x = 5.5 median = 1 In USE SALT (a) What does the fact that the mean is so much larger than the median tell you about the distribution of time spent volunteering per month? The fact that the mean is much greater than the median suggests that the distribution of times spent volunteering in the sample was negatively skewed. The fact that the mean is much less than the median suggests that the distribution of times spent volunteering in the sample was positively skewed. The fact that the mean is much greater…

The length of fish were measured at 3 different lakes. Is there evidence to suggest that the average length is not the same at all 3 locations? Lake 1: 3.5, 4.2, 2.1, 3.2, 1.7 Lake 2: 5.1, 6.2, 5.3,4.1 Lake 3: 5.6, 7.1, 6.4, 7.1, 6.4 What is your conclusion? There is not evidence that the mean length at one of the lakes is different then the others. There is evidence hat the mean length at a least one lake is different then the others.

For the residents in 2014, use R to calculate the interval with 99% certainty that the interval contains the actual population mean of the residents by census tracts. Type in the interval with keyboard. We also know that in each year, the number of residents by census tract in the State of Maryland follows a normal distribution, and the variance in the number of residents within the State of Maryland is the same for different years.
