Eight trials are simulated. the results are shown in the table. simulation 105 104 110 112 114 106 108 109 what is the estimated margin of error, using standard deviation? enter your answer, rounded to two decimal places, in the box. ±

2.897

Step-by-step explanation:

Let us find the mean and variance for the sample first.

105104110112

114106108109

Mean = sum/8 = 108.5

Variance = 12

Std dev = sq rt of variance = 3.464

Std error = std dev/ sq rt n

since n =8, we get std error = 1.225

Since sample size is small, df =8-1 =7

For 95% confidence intervals, t critical value for two tailed=2.365

Margin of error = std error x t critical = 1.225(2.365)

=2.897

the answer is 99.
