A research firm conducts a sample survey and discovers that 90% of people are more afraid of snakes than they are of flying. If a sample questionnaire collecting these results had 790 respondents, what is the margin of error (ME), rounded to the nearest thousandth?

Different values of margin of error for different significance level.

Step-by-step explanation:

We are given the following in the question:

p =  90% = 0.9

Sample size, n  790

We have to find the margin of error.

Formula:

Putting values, we get,

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
