To compare two programs for training industrial workers to perform la skilled job, 10 workers are included in an experiment. All
Alex17521 [72]

If we compare the p value and the significance level assumed  we see that  so we can conclude that we have enough evidence to reject the null hypothesis, and we can conclude the the true mean for method 1 is lower than the mean for the method 2 at 5% of significance.

<h3>Data given and notation</h3>

We can calculate the sample mean and deviation with these formulas:

represent the mean for the sample mean for 1

represent the mean for the sample mean for 2

represent the sample standard deviation for the sample 1

represent the sample standard deviation for the sample 2

sample size selected 1

sample size selected 2

represent the significance level for the hypothesis test.

t would represent the statistic (variable of interest)

represent the p value for the test (variable of interest)

State the null and alternative hypotheses.

We need to conduct a hypothesis in order to check if the average time taken when training under method 1 is less than the average time for Method 2, the system of hypothesis would be:

<h3>Null hypothesis:</h3>

Alternative hypothesis:

If we analyze the size for the samples both are less than 30 so for this case is better apply a t test to compare means, and the statistic is given by:

(1)

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

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

 P-value

The first step is calculate the degrees of freedom, on this case:

Since is a one sided test the p value would be:

Reconsider the determination of the hedge ratio in the two-state model where we showed that one-third share of stock would hedge
alexgriva [62]

Answer:

Upper state  = 135

Down State  = 92

Difference = 135-92= 43

<u>Exercise Price</u>                      <u>Hedge Ratio </u>

135                                       0/43 = 0.0000

122                                        13/43 = 0.302

112                                         23/43 = 0.535

92                                          43/43 = 1.000

Criticism is only good when you know about the problem beforehand.
statuscvo [17]
I assume this is a true or false question. 

False. 
Why is criticism needed anyway? Don't we have enough of that already?
We all know, by logic, what hurts others and what may bother them. Criticism is the act of picking on something with the intention of dislike. 

If further explanation is needed, just comment below and I'd be glad to assist.
