1.) The file cats.csv contains a data set consisting of the body weight (in kilograms) and heart weight (in grams) for 12 cats. Give the estimated regression line using the body weight as the predictor variable (x-variable) and the heart weight as the response variable (y-variable). Also, provide interpretations in terms of the problem for the slope and the y-intercept.
2.) The file cats.csv contains a data set consisting of the body weight (in kilograms) and heart weight (in grams) for 12 cats. Give the correlation coefficient and the coefficient of determination. Provide interpretations for both of these.
3.) The file cats.csv contains a data set consisting of the body weight (in kilograms) and heart weight (in grams) for 12 cats. Give the point estimate and 99% confidence interval for the mean heart weight of cats whose body weights are 2.4 kilograms. Give an interpretation for the 99% confidence interval.

1.) The file cats.csv contains a data set consisting of the body
weight (in kilograms) and heart weight (in grams) for 12 cats. Test
at the 5% significance level that a positive linear relationship
exists between the body weight of cat and their mean heart weight.

The data file contains the Body Mass Index (BMI) for a sample of
men and a sample of women. Two of the columns, OW_male and
OW_female code the BMI values as: 0 - if BMI ≤ 25.4 (these are
considered “not overweight”); 1 - if BMI >= 25.5 (these are
considered “overweight”). (a) Test whether there is sufficient
evidence to show that the proportion of overweight males
(proportion of males who are overweight) is different than the
proportion of overweight...

The data set contains the weight (grams) of 10 mice before and
after the treatment. Weight of the mice before treatment
before:
(200.1, 190.9, 192.7, 213, 241.4, 196.9, 172.2, 185.5, 205.2,
193.7)
Weight of the mice after treatment after:
(392.9, 393.2, 345.1, 393, 434, 427.9, 422, 383.9, 392.3,
352.2)
Is there enough evidence in the data that the treatment
increases the weight population average weight by at least 150
grams?

please show work
Body mass index (BMI) is computed as the ratio of weight in
kilograms to the square of the height in meters. The
distribution of BMI is approximately normal for females aged 30-39.
In this group, the mean BMI is 24.5, with a standard deviation of
3.3.
13) What proportion of females aged 30-39 has a BMI of 25 or
more?
14) Persons with a BMI of 30 or greater are considered
obese. What proportion of females aged 30-39 is...

PotashCorp
The data set in the file ch18_MCSP_PotashCorp
contains average quarterly share prices for PotashCorp and prices
for potash mineral. Investigate the relationship between these
variables. (a) Some people think that if the share price of a
mining company is high, that is because investors expect high
mineral prices for thecorresponding quarter. Can the potash price
be estimated from the PotashCorp share price? The data includes a
period when the price of potash mineral was exceptionally high. If
you eliminate...
