<span>Revenue is the specific amount of money that a company receives during a set period of time. If the cards are selling for $3 each, then the income generated from the sales of the cards can be calculated by $3 x 20,000. This results in $60,000. Then, you can subtract the income generated from the cards from the cost of the cards to produce the actual revenue. $200,000 - $60,000 = $140,000. There is no revenue yet this month, because they have not sold enough cards.</span>

The average college lecture hall (auditorium) can seat 60 students with a standard deviation of 21. Assume that a total of 60 le
fiasKO [112]

Answer:

The standard deviation of the sample mean is  \sigma _ {\=  x } = 2.711

Step-by-step explanation:

From the question we are told that

   The mean is  \= x  =  60

    The standard deviation is  \sigma  =  21

     The sample size is n  =  60

Generally the standard deviation of the sample mean is mathematically represented as  

               \sigma _ {\=  x } =  \frac{\sigma  }{\sqrt{n} }

substituting values

               \sigma _ {\=  x } =  \frac{ 21 }{\sqrt{60} }

               \sigma _ {\=  x } = 2.711

You want to test the claim that the average age of students at Gorka College is greater than the average age of students at Yapo
777dan777 [17]

Answer:

Kindly check explanation

Step-by-step explanation:

The hypothesis :

H0 : μ1 = μ2

H1 : μ1 > μ2

Given :

x1 = 21.1 ; n1 = 53 ; s1 = 1.1

x2 = 20.7 ; n2 = 46 ; s2 = 1.2

The test statistic :

(x1 - x2) / √[(s1²/n1 + s2²/n2)]

(21.1 - 20.7) / √[(1.1²/53 + 1.2²/46)]

0.4 / 0.2326682

Test statistic = 1.719

The degree of freedom using the conservative method :

Comparing :

Degree of freedom = n - 1

Degree of freedom 1 = 53 - 1 = 52

Degree of freedom 2 = 46 - 1 = 45

Smaller degree of freedom is chosen ;

The Pvalue from Test statistic, using df = 45

Pvalue = 0.0462

Pvalue < α ; Hence, there is significant evidence to conclude that average age of Gorka student is higher than Yaphoa.
