In calculations of sample size for proportions, q refers to the proportion of the population that does not have the attribute of interest.

∴ option c) the proportion of the population that does not have the attribute of interest is correct.

Step-by-step explanation:

Given that in calculations of sample size for proportions.

To find q refers :

In the calculation of sample size in proportion p is the sample proportion.

p is the proportion of the population that does have the attribute of interest.

We know that p+q=1

That is Every probability of success and failure is 1

p+q=1

⇒ q=1-p refers to the failure of p

Hence q is the the proportion of the population that does not have the attribute of interest

∴ option c) the proportion of the population that does not have the attribute of interest is correct

∴ In calculations of sample size for proportions, q refers to the proportion of the population that does not have the attribute of interest

Answer from: Quest

step-by-step explanation:

not really sure

Answer from: Quest

$a_1 = 1$ , and

$a_{n+1} = a_n + (n + 1)$ for $n \ge 1$

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote $a_1 = 1$ , $a_2 = 3$ , $a_3 = 6$ , so that we can call

1 the 1st term, 3 the 2nd term, 6 the 3rd term,etc.

note the following:

from the 1st term (1) to the 2nd term (3), we go up by 2,from the 2nd term (3) to the 3rd term (6), we go up by 3from the 3rd term (6) to the 4th term (10), we go up by 4, andfrom the 4th term (10) to the 5th term (15), we go up by 5.

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 $a_1 = 1$ , to get to $a_2 = 3$ , we add $2(=1+1)$

from $a_2 = 3$ , to get to $a_3 = 6$ , we add $3 (=2+1)$

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

$a_1 = 1$ , and $a_{n+1} = a_n +(n + 1)$ for $n \ge 1$
