Use the data from question 2. If the data are normally distributed find the percentage of these families who spent : $167 per day 91.8% less than 367 per day 93.32% more than 247 per day 50% $350 per day 4.27% less than $67? Between$200 and $300 per day? Between $360 and $400 per day? More than the median? Less than the mean?

if you need , reply with more info. u.

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

, and for

answer: it is 8
