Please answer both!!
Suppose the national average dollar amount for an
automobile insurance claim is $805.66. You work for an agency in
Michigan and you are interested in whether or not the state average
is less than the national average. The hypotheses for this scenario
are as follows: Null Hypothesis: μ ≥ 805.66, Alternative
Hypothesis: μ < 805.66. You take a random sample of claims and
calculate a p-value of 0.02 based on the data, what is the
appropriate conclusion?...

Question 1 (1 point)
Suppose the national average dollar amount for an automobile
insurance claim is $746.9. You work for an agency in Michigan and
you are interested in whether or not the state average is different
from the national average. Treating the national mean as the
historical value, What are the appropriate hypotheses for this
test?
Question 1 options:
1)
HO: μ ≤ 746.9
HA: μ > 746.9
2)
HO: μ > 746.9
HA: μ ≤ 746.9
3)
HO:...

You want to see if there is a statistical difference between the
two groups. Run descriptives and a two-tailed, two sample assuming
equal variance t-test.

A physiological experiment was concluded to study the effect of
various factors on a pulse rate. The participants took their own
pulse. They then were asked to flip a coin. If their coin came up
head, they were to run in place for 1 minute. Then everyone took
their own pulse again. The dataset pulse.txt, available from
Moodle, contains the following variables: ROW- id numbers, from 1
to 92; PULSE1- first pulse rate; PULSE2- second pulse rate;
RAN-1=ran in place,...
