Assume that the two variables are related according to the simple linear regression model. 1. The least squares estimate of the slope is .Round to 1 decimal place. 2. The least squares estimate of the intercept is . Round to 1 decimal place. 3. If the Hammett constant x is set to 0.17, what is the predicted maximum absorption? Round to 1 decimal place. 4. The observed value of maximum absorption at x = 0.17 is y = 301. What is the value of the coresponding residual? Round to 1 decimal place. 5. The totell sum of squares of y is and the error sum of…

15. (Percentile, median) The pth percentile of a sample is a number Q, such that at least p% of the sample values are smaller than or equal to Q, and also at least (100 – p)% of those values are larger than or equal to Q. If there is more than one such number (in which case there will be an interval of them), the pth percentile is defined as the average of the numbers (midpoint of that interval). In particular, Q50 is called the middle quartile or median and is denoted by r. Find for the sample in Table 24.2 (Sec. 24.3).

. At wind speeds above 1000 cm/sec, significant sand–moving events begin to occur. Wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. The cyclic nature of wind and moving sand determines the shape and location of large dunes. At a test site, the prevailing direction of the wind did not change noticeably. However, the velocity did change. 75 wind speed readings gave an average velocity of x =1045 cm/sec. Based on long–term experience,  can be assumed to be 240 cm/sec Find a 99% confidence interval for the population mean wind speed at this site.
