14 divided by 10.22 show me the steps to get the right answer.

First put 10.22 inside the division sign. Then, put 14 on the outside. 14 cant go into 10 so add a decimal at the top before you start writing numbers. 14 goes into 102, 7 times before going over. 14 times 7 is 98. 102-98 is 4. Then get the 4 and drop the 2. 14 goes into 42, 3 times. Your answer would be .73. Hope this helps. ;)

 

Comparing the p value with the significance level assumed is we see that so we can conclude that we have enough evidence to reject the null hypothesis, and the mean for males is significantly higher than the mean for female.  

Step-by-step explanation:

Data given and notation  

represent the mean for the sample male

represent the mean for the sample female

represent the sample standard deviation for the males  

represent the sample standard deviation for the females  

sample size for the group male  

sample size for the group female  

t would represent the statistic (variable of interest)  

Concepts and formulas to use  

We need to conduct a hypothesis in order to check if the mean for males students is higher than the mean for female students, the system of hypothesis would be:  

Null hypothesis:  

Alternative hypothesis:  

We don't have the population standard deviation, so for this case is better apply a t test to compare means, and the statistic is given by:  

(1)

And the degrees of freedom are given by  

t-test: Is used to compare group means. Is one of the most common tests and is used to determine whether the means of two groups are equal to each other.

Calculate the statistic

With the info given we can replace in formula (1) like this:  

What is the p-value?

Since is a right tailed test the p value would be:  

 

Comparing the p value with the significance level assumed is we see that so we can conclude that we have enough evidence to reject the null hypothesis, and the mean for males is significantly higher than the mean for female.
