Answer:
The null and alternative hypotheses are:
Under the null hypothesis, the test statistic is:
Where:
is the sample mean
is the sample standard deviation
is the sample size
Now, we can find the right tailed t critical value at 0.01 significance level for df = n-1 = 10 - 1 = 9 using the t distribution table. The t critical value is given below:
Since the test statistic is less than the t critical value, we therefore, fail to reject the null hypothesis and conclude that there is not sufficient evidence to support the claim that the people do better with the new edition.
The fraction you are looking for is expenses/earnings
So (2500+650+434)/3600
=224/225
If you want to turn this into a percentage just multiply by 100, to give you 99.56%.
The denominator in the earnings per share formula is number of common shares outstanding.
What is the denominator used in the computation of earnings per share?
- The weighted average of the outstanding shares of common stock serves as the numerator of the earnings per share.
- The "per share" part necessitates further computation when the number of common shares changes in the middle of the year.
- The weighting of the per share part depends on how long each share number has been in circulation.
How are basic earnings per share determined?
- Basic EPS is calculated by dividing net income by the weighted average of the common shares outstanding for the relevant period.
- Preferred dividends should be removed from the net income because they are not available to common stockholders.
- Net income can also be broken down into "continuing operations" P&L and "total P&L".
