Bottling Company The mean, median and standard deviation are as follows: Bottle No. Oz mean median std dev The 95% confidence interval can be calculated as follows: CI = x +/- t* (s/?n) CI = 14.87 +/- 2.045 * (0.541 / ?30) CI = 14.87 +/- CI = 14.668 to 15.07 The null hypothesis is that the bottles are within the 95% confidence interval of 16oz as required by law. So the number of samples that fall within 15.8 to

Calculate Touring Enterprises' weighted average cost of capital (WACC). Work as follows: first, compute the after-tax cost of debt, then compute the cost of equity. WACC = E/V x Re + D/V x Rd x (1 - Tc) Re = cost of equity Rd = cost of debt E = market value of the firm's equity D = market value of the firm's debt V = E + D = firm value E/V = percentage of financing that

A standard deviation is so "standardized" that, generally speaking, 70% of the data points will fall within one standard deviation, and 90% of the data points will fall within two standard deviations. Standard deviation is one of the most common ways for researchers to describe data as it forms a basis for comparing data from study to study. Measures of central tendency are most effective at describing data that shows

These low scores represent persons whose handling skills for fragile material are weak and are a potential risk to the company. In group B, the handling skills of the group members are very similar. Group B. also had the lower standard deviation 12.43 as compared to 22.71. The standard deviation is a measure of the difference in skill between the group, the larger the standard deviation, then the greater the

Using this data set we can calculate mean, median, mode, and standard deviation for this data set over last 20 years: Mean can be found according to the following formula: So mean February temperature equals to 33.825 F Median of the data is the middle score after data has been set in order, so February temperature median equals to 33.7 F Mode of the data is the value from data set which occurs

GPA is interval level data one can report all measures of central tendency and dispersion (Creswell, 2012). In the original data case 38 had a GPA reported as 9.00. This value is of course impossible and since there were no missing values defined in the data set this case was treated as missing data. If used as reported it would have resulted in a much larger standard deviation and
