**Learning Goal:**I’m working on a linear algebra multi-part question and need an explanation and answer to help me learn.

Hello,

Please answer the problems below mentioned in PDF and attached materials also in Hand written solved problems and excel also

Problem 1: For the given data below, determine (a) the mean, (b) the standard deviation, (c) the variance, (d) the coefficient of variation, and (e) the 95% confidence interval for the mean. Also (f) construct a histogram using a range from 7.5 to 11.5 with intervals of 0.5.

Problem 2: Use least-squares regression to fit a straight line to x 6 7 11 15 17 21 23 29 29 37 39 y 29 21 29 14 21 15 7 7 13 03 Along with the slope and the intercept, compute the standard error of the estimate and the correlation coefficient. Plot the data and the regression line. If someone made an additional measurement of x = 10, y = 10, would you suspect, based on a visual assessment and the standard error, that the measurement was valid or faulty? Justify your conclusion.
