Imagine you are in charge of planning a chili cook-off competition among several cooking teams, sponsored by asi here at csueb.
you want to make sure that there are enough plates of chili for all pre-paid tasters. csueb has a total student body of about 13,000.
you have the following standards you must meet: a confidence level of 99%, and an error of no more than four ounces per cooking team. last year’s competition had a standard deviation of 30 ounces for the amount of chili cooked.

a. what is the necessary minimum sample size?

b. how is the sample size impacted if we change our confidence level to 90%?

c. how is the sample size impacted if we change the error requirement to no more than two ounces per cooking team?

d. explain how determining sample size for the campus chili competition represents statistical, financial and organizational challenges.

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

the equation is not included but the answer is (1.50, 2.00, 2.75)
