a research center base in Canada used data sample of 25 university that over degree programme to investigate the nature of relationship between annual salaries of graduates Y and annual tuition fees X of these institutions .all measured in thousand of dollar per year . Preliminary analysis of the sample data produced the following sample information. summation Y=1034.97, summation Y^2 = 45237.19, summation X=528.599, summation X^2 = 11432.92 ,summation XY = 22250.54, n = 25. Use the above information to obtain the ordinary least square (OLS) estimate b1 cal and b2 cal and interpret the estimated equation of the regression line

The research center of a university collects data on employment
and hourly earnings in private industry groups. Eighteen people
working in the manufacturing industry are selected at random. Their
average hourly earnings, in dollars, are as follows.
52.6 45.9 62.0 74.2 80.6 77.5 34.8 46.8 48.4 68.7 41.2 52.5 58.9
66.2 69.9 57.1 63.3 102.9
(a) Construct a frequency distribution and a relative frequency
distribution for these hourly earnings. Use a first cutpoint of 34

The accompanying data on degree of spirituality for a sample of
natural scientists and a sample of social scientists working at
research universities appeared in a paper. Assume that it is
reasonable to regard these two samples as representative of natural
and social scientists at research universities. Is there evidence
that the spirituality category proportions are not the same for
natural and social scientists? Test the relevant hypotheses using a
significance level of 0.01.

Dr. Micheal Osterholm, director of the Center for Infectious
Disease Research and Policy at the University of Minnesota, in an
interview with Chuck Todd on Sunday May 10, claimed that some
COVID-19 tests have 50% false positives. Assuming that the same
test has 2% false negatives, calculate
(a) Probability that a person who tested positive is really
infected with COVID-19 virus.
(b) Probability that a person who tested negative is not
sick.
As of today, there are 1.37 million confirmed...

A research center claims that at least 25% of adults in a
certain country think that their taxes will be audited. In a random
sample of
600 adults in that country in a recent year, 22% say they are
concerned that their taxes will be audited. At α=0.100.10,
is there enough evidence to reject the center's claim? Complete
parts (a) through(e) below.
