A new fertilizer was applied to the soil of 146 bean plants. 23% showed increased growth. Find the margin of error and 95% confidence interval for the percentage of all bean plants which show increased growth after application of the fertilizer. Round all answers to 2 decimal places.

The significance level for this case would be and the critical value for this case would be:

The margin of error is given by:

And replacing we got:

And the margin of error for this case would be

Step-by-step explanation:

For this case we have the following dataset given:

represent the sample size

represent the estimated proportion of interest

represent the confidence level

The significance level for this case would be and the critical value for this case would be:

The margin of error is given by:

And replacing we got:

And the margin of error for this case would be

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
