Answer:
The claim cannot be true because any probability is between 0 and 1.
Step-by-step explanation:
4 times 0.30 is 1.20, a value that cannot be a probability. Any probability will be between 0 and 1 (inclusive).
The claim cannot be true because any probability is between 0 and 1.
Answer:
2.897
Step-by-step explanation:
Let us find the mean and variance for the sample first.
105 104 110 112
114 106 108 109
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
Because if you draw a three pies and cut all of them into 8 pieces and
shade 6 in one, 5 in the other, and 7 into the last one, you will see
that there is a bigger piece shaded in the one with 6 shaded than the
pie with 5 shaded. And less shaded than the one with 7 shaded.
