Question

The following sample of six measurements was randomly selected from a normally distributed population: 2,5,−2,7,2,4. (a.)Test the null hypothesis that the mean of the population is 2 against the alternative hypothesis, μ < 2. Use α=.05. (b.)Test the null hypothesis that the mean of the population is 2 against the alternative hypothesis, μ isn't equal to 2. Use α=.05. (c.) Find the observed significance level for each test.

Answer #1

Assume that a simple random sample has been selected from a
normally distributed population and test the given claim.
Test
the given claim. Identify the null hypotheses, alternative
hypothesis, test statistic, P-value,
critical value(s), conclusion about the null hypothesis, and final
conclusion for the
original claim. Try both ways the P-valued method and traditional
method.

Assume that a simple random sample has been selected from a
normally distributed population and test the given claim. Use
either the traditional method or P-value method as indicated.
Identify the null and alternative hypotheses, test statistic,
critical value(s) or P-value (or range of P-values) as appropriate,
and state the final conclusion that addresses the original claim. A

normally distributed population and test the given claim. Identify
the null and alternative hypotheses, test statistic, P-value, and
state the final conclusion that addresses the original claim. A
coin mint has a specification that a particular coin has a mean
weight of 2.5 g. A sample of 36 coins was collected. Those coins

Suppose a random sample of size 22 is taken from a normally
distributed population, and the sample mean and variance are
calculated to be x¯=5.29 and s2=0.5 respectively.
Use this information to test the null hypothesis
H0:μ=5 versus the alternative hypothesis HA:μ>5 .
a) What is the value of the test statistic, for testing the null
hypothesis that the population mean is equal to 5?
Round your response to at least 3 decimal places.
b) The p-value falls within which one of...

For the general population, IQ test scores are normally
distributed with a mean of 100 and a variance of 225.
The IQ scores for a sample of 81 randomly selected chemical
engineers resulted in a variance of 144.
We want to test the claim that the variance for chemical
engineers is less than that of the general population.

Hypothesis?
2. If we use a 0.01 significance level, what is the critical...

Assume that a simple random sample has been selected from a
normally distributed population. We want to test the claim that for
the population of female college students at a particular
university, the mean weight is given by μ=155lb. The sample data
are summarized as follow: n=20, x=160lb, and s=18.5 lb. Use a
significant level of α=0.5. a. Identify the relevant variable and
parameter b. State null and alternative hypothesis c. Find the test
statistic value d. Find and interpret...

(S 10.3) Suppose a random sample of size 15 is taken from a
normally distributed population, and the sample mean and variance
are calculated to be x¯=5.22 and s2=6.5respectively. Use this
information to test the null hypothesis H0:?=5versus the
alternative hypothesis HA:?<5, at the 10% level of significance.
What is the value of the test statistic, for testing the null
hypothesis that the population mean is equal to 5?____________
Round your response to at least 3 decimal places.

Assume that a simple random sample has been selected from a
