The district manager of four different restaurants wanted to investigate whether the four restaurants differed with respect to c

ustomers ordering dessert or not based on family classification (with children or without children). Independent random samples of 100 customers who ordered dessert were selected from each restaurant, and the customers were identified as either being with children or without children. After verifying the conditions for the appropriate hypothesis test, the manager calculated a chi-square test statistic of 6.45 with an associated

Answer:

<em>Hello your question is incomplete attached below is the complete question</em>

answer : There is not convincing statistical evidence to suggest that the proportion of customers who order dessert at each restaurant is not the same based on family classification. ( E )

Step-by-step explanation:

To arrive at this conclusion we will determine the Null and alternate hypothesis

<em>H0 : Number that orders dessert is same based on family classification given</em>

<em>Ha : Number that orders dessert is not the same based on family classification given </em>

from the question the p-value of Chi-square test is 0.092 > 0.05 hence we will fail to reject the null hypothesis. therefore we can conclude that

There is not convincing statistical evidence to suggest that the proportion of customers who order dessert at each restaurant is not the same based on family classification

Marta is solving the equation S = 2πrh + 2πr^2 for h. Which should be the result?
olga_2 [115]

Answer:

h = \frac{S}{2πr} - r


Step-by-step explanation:

The question requires you to make h the subject of the formula.

S = 2πrh + 2πr²

subtract 2πr² on both sides.

S - 2πr² = 2πrh - 2πr² -  2πr²

S - 2πr² = 2πrh

Dividing both sides by  2πr

(S -  2πr²)/2πr =  2πrh/ 2πr

h = \frac{S}{2πr} - r

Help me pleaseeeee?!
den301095 [7]

Answer:

#1: -1.5, -0.5, 1/2, 1.5

#2:  -3, -1, 1.2, 2.3

Step-by-step explanation:

#1

First we have to figure out the correct order before we plot.

Find the biggest number:

looking at the number the biggest would be 1.5

Find the smallest number:

Looking at the number the smallest would be -1.5

Now that we have that we can easily figure out the rest...

(Going from least to greatest; like on a number line)

-1.5, -0.5, 1/2, 1.5 (That is how you will place the first one)

#2

(Use the steps from above to find the answer)

Biggest: 2.3

Smallest: -3

Order: -3, -1, 1.2, 2.3 (Placing on number line use that order)

Hope this helps :)

A person trying to gain access to a bank vault must pass through a series of three security doors. If an attempt to pass through
ExtremeBDS [4]

Answer:

C) S = {F, PF, PPF, PPP}

Step-by-step explanation:

For this case, we know that a person is trying to gain access to a bank vault and needs to go through 3 security doors, and we know that if the person does not pass a door, then he/she has no other attempts. We denote P= Successful pass , F= Failed pass

And we are interested on the sample space, we need to remember that the sample is the set with all the possible values for an experiment.

For this case the person can fail at the 1,2 or 3 try

For the case that fails at the 1 try we have F

For the case that fails at the 2 try we have PF

For the case that fails at the 3 try we have PPF

And the last option is that the person not fails at any try and we have PPP

So then the sample space would be given by:

C) S = {F, PF, PPF, PPP}
