In a random sample of 520 adults, the mean was 150 and the standard deviation was 4.5. the study was reported with a 95% confidence level, and the confidence interval for the study was 150 ± 0.39. what range of values shows the confidence interval for the study? 146.1 to 153.9 149.61 to 150.39 150 to 150.39 150 to 153.9

What range of values shows the confidence interval for the study?

149.61 to 150.39

A confidence level of 95% means:

95% of the time, population data will fall between 149.61 and 150.39.

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
