Manufacturing companies strive to maintain production consistency, but it is often difficult for outsiders to tell whether they have succeeded. Consider a company that makes a certain brand of candy claims that 9% of the candies it produces are red and that bags are packed randomly. Their production controls can be checked by sampling bags of candies. Suppose bags containing about 280 candies are opened and the proportion of red candies is recorded. Complete parts a through c. a) Explain why it's appropriate to use a Normal model to describe the distribution of the proportion of red candies they might expect in the 280-candy bag. It's appropriate to use a Normal model because npequals 25.2 and nqequals 254.8, which at least one of is greater than or equal to 10. The samples in each bag should be random. (Type integers or decimals. Do

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
