Introduction:
Mean is a model of a given data set. It is the value that is the most common in a given set. Mean or average of a sample is calculated by summing all the values in the sample and dividing them by the total number of individuals in the sample (n). Variance is a numerical measure of the spread of the distribution around the mean. This is calculated to determine how much variation exists among individuals in the sample. It is calculated by summing the square of the difference between each individual value and the sample mean and dividing that sum by the number of degrees of freedom in the sample. Standard deviation describes the distribution of data. It is calculated as square root of variance.

The relationship between weight (in kilograms) and gender was estimated as below in a linear format.
(Male was coded as 0 and Female was coded as 1.)
Weight = -10.23 * Female + 66.73
(The p-value for the coefficient of Female is 0.03.)
Base on the above equation, which of the following statements are true? (Select all that apply. There can be more than one answer.)
Answer options:
In the sample used to estimate the equation, the average weight of females is 66.23 kilograms
In the sample used to estimate the equation, the average weight of females is 56.5 kilograms
In the sample used to estimate the equation, the average weight of males is 66.73 kilograms
Females are expected to weigh 10.23 kilograms less than males

- Upon comparing the mass of Fuji apples grown on two farms in Georgetown, KY--one using organic fertilizer and a neighboring farm using commercial fertilizer, the a research program commissioned by the USDA finds that the mean mass of organically and commercially grown apples are 224.2 g and 224.6 g, respectively. The standard error for both means is 0.015 g. The statistical test obtained by comparing the mass of several thousand apples from each farm (organic: 6,000, commercial: 78,000) produced a p-value of 0.001. What is correct interpretation of the results? The apples from the non-organic apples tend to be heavier than organic apples. There is no discernible difference in the mass of apples grown on both farm; this is supported by the statistically significant P-vale of 0.001. O Apples from the commercial farm were heavier than those from the organic farm, and this difference is statistically significant. O The difference in mass of apples from the two farms is negligible.arrow_forwardI'm needing help with part 1 through 3, please The data of Sugar Water and Plain Water: mean # of drops variance degrees of freedom t stat t crit (from the table) plain water 25.3 17.221 38 -4.01 2.0261 sugar water 21.3 21.256 1.
