Answer:
The test statistic is z = 1.865.
Step-by-step explanation:
The test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis,
is the standard deviation and n is the size of the sample.
H0: p = 0.11
This means that 0.11 is tested at the null hypothesis, and so:
The engineer weighs 94 bags and finds that 16 of them are over-filled.
This means that:
What is the test statistic?
The test statistic is z = 1.865.
F = 9/5(40) + 32
F = 72 + 32
F = 105
40°C is ~105°F, and the closest would be D.
Answer:
The 95% confidence interval is
Step-by-step explanation:
From the question we are told that
The sample size is n = 26
The mean is
The standard deviation is
From the question we are told the confidence level is 95% , hence the level of significance is
