Question

We have two samples of people who took a literacy test, termed
Literacy A and Literacy B which are from two different states.
Researches are interested if there's a difference in literacy
between the two states.

Literacy A Literacy B

9.6. 24

8.9. 10

11.4. 20.7

7.2. 11.4

9.2. 4

-0.3 -4.5

2.2. 22.2

-4.5. -4.5

6.6. 6.6

7.3. 7.3

11.5. 11.5

8.6. 8.6

3.4. 3.4

2.2. 2.2

18.4. 18.4

-4.8. -4.8

Answer #1

from the fisher exact test in the R studio,

p value is greater than 0.05 (level of significance).

Therefore we accept the Null hypothesis at 5% level of significance.

I.e. we can conclude that,

There is no difference in the Literacy of two states .

Use the data in Bank Dataset to answer this question.
Construct a 95% confidence interval for the mean increase in
deposits. Note that the population standard deviation σ is not
known in this case. Instead the sample standard deviation s should
be calculated from the sample and the t distribution should be
used.
2. What is the margin of error at the 95% confidence level?
Bank Dataset of Increase in deposits. Mean is 4. Sample size is
152 customers.
4.3...

An important statistical measurement in service facilities (such
as restaurants and banks) is the variability in service times. As
an experiment, two bank tellers were observed, and the service
times for each of 100 customers were recorded. Do these data allow
us to infer at the 5% significance level that the variance in
service times differs between the two tellers? Estimate with 95%
confidence the ratio of variances of the two bank tellers. Teller 1
Teller 2 7.2 10.9 5.4...

We want to compare the
soil water content (% water by volume) of two fields growing bell
peppers.
The claim is that the two fields have different soil water
content.
Use the data below to test the hypothesis that the fields have
different soil water content.
Field 1 is in list1 and Field 2 is in list2.
We do not know whether the water content values are normally
distributed or not, but their variances are equal.
Provide your answers below....

We wish to determine the impact of Specification Buying, X11, on
Satisfaction Level, X10. To do so we will split the Hatco data file
into two separate data sets based on the Specification Buying, X11.
This variable has two categories:
1=employs total value analysis approach, evaluating each
purchase separately;
0 = use of specification buying.
Sort the entire Hatco data set based on Specification Buying.
This will create two separate groups of records. Those records with
X11 = 0 and...

Using the two-sample hypothesis test comparing old call time to
new call time at a .05 level of significance, discuss the
hypothesis test assumptions and tests used. Provide the test
statistic and p-value in your response. Evaluate the
results of the hypothesis test with the scenario. Provide
recommendations for the vice president.
Using new call time and coded quality, develop a prediction
equation for new call time. Evaluate the model and discuss the
coefficient of determination, significance, and use the...

Med Student Sleep Average (Raw Data, Software Required): Here we
consider a small study on the sleep habits of med students and
non-med students. The study consists of the hours of sleep per
night obtained from 30 non-med students and 25 med students. The
sample data is given in the table below. Test the claim that, on
average, the mean hours of sleep for all med students is different
from that for non-med students. Test this claim at the 0.05...

Census data was collected on the 50 states and Washington, D.C.
We are interested in determining whether average lifespan (LIFE) is
related to the ratio of males to females in percent (MALE), birth
rate per 1,000 people (BIRTH), divorce rate per 1,000 people
(DIVO), number of hospital beds per 100,000 people (BEDS),
percentage of population 25 years or older having completed 16
years of school (EDUC) and per capita income (INCO).

In R, if I have a plot of LIFE against BIRTH and I want to
specifically mark the data point corresponding to STATE "AK" in the
graph as red colour(the rest of the points as black color), what R
command should we use?(Please don't look through the data to find
AK's birth value(24.8)or life value (69.31)and mark this point
manually referring to this value as other state can have the same
birth and life value)
