1. Use a random number generator to randomly select four samples from the population. This time. make the samples of size n = 10. Record the samples in Table 7'26 e' . As before, for each sample, calculate the mean to the nearest tenth. Record them in the spaces provided. Record the sample means for the rest of the class. Sample lsample 2Sample SSample 4Sample means from other groups Means: x' = ____ x' = ____ x' = ____ x'x= ____ Tablelo 2. Calculate the following: a. x' = ______ b. 5x- = ______ 3. For the original population, construct a histogram. Make intervals with a bar width of one day. Sketch the graph using a mler and pencil. Scale the axes. Framer \"M10313! Figure 7.13 4. Draw a smooth curve through the tops of the bars of the histogram. Use one to two complete sentences to describe the general shape of the curve
