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

A random sample of 70 observations from a normally distributed
population possesses a sample mean equal to 26.2 and a sample
standard deviation equal to 4.1
Use rejection region to test the null hypothesis that the mean
of the population is 28 against the alternative hypothesis,
μ<28 use α = .1
Use p-value to tell the null hypothesis that the mean of the
population is 28 against the alternative hypothesis that the mean
of the population is 28 against the...

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

Assume that a simple random sample has been selected from 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
have a mean weight of 2.49427 g and a standard deviation of 0.01141
g. Use a...

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.
1. What is the Null Hypothesis and the Alternative
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
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
