A restaurant chain wants to change their oil from peanut oil to canola oil in order to save money. However, the restaurant wants

to survey their customers to see which oil they prefer. For one month, the restaurant serves food cooked in peanut oil and for the next month they serve food cooked with canola oil. Surveys are sent out with guests which ask to rate their fried food on a scale of 1 to 7. The results of the returned surveys are given below. Is there enough evidence to conclude that there is no difference in the satisfaction level of the customer? Use a level of significance of 2%.
Peanut Oil Canola Oil
n1 = 108 n2 = 87
x⎯⎯1x¯1 x⎯⎯2x¯2
s1 = 2.25 s2 = 3.18

1. What is the p-value for this hypothesis test? Round your answer to four decimal places.

In tests of a computer component, it is found that the mean time between failures is 937 hours. A modification is made which is supposed to increase reliability by increasing the time between failures. Tests on a sample of 36 modified components produce a mean time between failures of 960 hours, with a standard deviation of 52 hours. Is there enough evidence to support the claim that, on average, the modified components last longer than 937 hours between failures? Use a level of significance of 5%.

2. What is the p-value for this hypothesis test? Round your answer to four decimal places.

Can anyone help me please? I really need it.
Artemon [7]
First you set f(x) and h(x) equal to each other. So 1/x+1=2x+3. Next, you multiply each side by 1 to cancel out the fraction. So now the answer is x+1=2x+3. Now subtract 1 from each side. X=2x+2. Subtract 2x from each side now. -2x=2. Divide by -2x and get the answer x= -1

Please solve these soon I have to turn thin in tomorrow !!!!!!!!
Gnoma [55]

Answer:

a) so if you're looking for a then you substitute the a in the problem so the real question would be answered by simply doing this. 3 times (do this first) 6 times 3. so it would end up looking like this if you did it in your head. 6x3=18 then 18x3= 54 so the answer for ten after you did all the math would equal out to be 54.

d) so you're going to substitue the d again, for what it tells you d equals. in this case, d= a negative 2 so, 5 x do this first -2 x 4 = so if you did this in your head you would end up with -2 x 4 = -8 because anything times a negative is turned into a negative. so that is why the answer is -8 for the first part. then you multiply that answer by 5 because we all like the 5 dollar foot longs. so carry that into an answer of - 40. because we all know we want to be younger once we reach 40.

r) 5times -3 equals -15 times 2 would be... ding ding ding 30 because a negative times a negative is a positive. think of negatives this way. when you frown it's your smile upside down. ok so a frown is a negative, if you multiply a negative to a negative it's like turning your frown upside down. so you end up with a positive! ok?! so there. the secrets of life and math.

call me for the rest of the answers... this is too much to write down.
