**Problem:** For the data 4, 16, 20, 24, 38, 57, 59, 60, 60, 74, compute the 10% trimmed mean.**Solution Explanation:**The 10% trimmed mean involves removing the top 10% and the bottom 10% of data points before calculating the mean. Here's how to compute it for the given data set:1. **Order the data set:** Arrange the given numbers in ascending order. - Ordered data: 4, 16, 20, 24, 38, 57, 59, 60, 60, 742. **Determine the number of data points to trim:** With 10 data points: - Trim 10% of 10 = 1 data point from each end.3. **Trim the data:** Remove the lowest and highest data points. - Trimmed data: 16, 20, 24, 38, 57, 59, 60, 604. **Calculate the mean of the trimmed data:** - Mean = (16 + 20 + 24 + 38 + 57 + 59 + 60 + 60) / 8 - Mean = 334 / 8 - Mean = 41.75Thus, the 10% trimmed mean of the data set is 41.75.

Given data : 4,16,20,24,38,57,59,60,60,74 n = 10

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.
