Explanation of Solution
Null hypothesis
- The null hypothesis is about the advertising budgets of TV, radio or newspaper having no effect on sales.
- The corresponding p-values are highly significant for TV and radio but not significant for newspaper.
- Hence it is concluded that newspaper advertising budget do not affect sales.

One question in the survey asked how much time per year the children spent in volunteer activities. The sample mean was 14.76 hours and the sample standard deviation was 16.54 hours. USE SALT Based on the reported sample mean and sample standard deviation, explain why it is not reasonable to think that the distribution of volunteer times for the population of South Korean middle school students is approximately normal. (Round your answer to nearest percent.) If the distribution of volunteer times is approximately normal, for the sample standard deviation of s = 16.54 hours and the sample mean of x = 14.76 hours, approximately 19 negative. Therefore, it is not reasonable to think that the distribution of volunteer times is approximately normal. % of…arrow_forward
- In python, for a sample data with 4 columns and 60 rows how do you find the parameters for the regression with the feature map (see attached) where we consider the loss function to be the square of residuals. Once this is done, how do you compute the empirical risk? I've attached some of the data below, it would be sufficient to see how you get results for the question using the above dataset. 1 14 25 620 -1 69 29 625 0 83 27 850 0 28 25 1315 1 41 25 2120 -1 153 31 1315 0 55 25 2600 0 55 31 490 1 69 25 3110 1 83 25 3535arrow_forwardImagine a regression model on a single feature, defined by the function f (x) = wx + b where X, W, and b are scalars.
