Sony claims that 55% of of the world population have their
products. You think it’s different. You simple
random sample x “159” people and y “76” say that they have
products.
Is there sufficient evidence at the 5% significance level (α =
.05) to indicate that the percent of people with products is
different than 55%
show all work (or tell me what you plug into your calculator).
Use specific words like you would in class.

The data below represents height in inches/weight in pounds.
Clearly identify the dependent and independent variables as well as
the domain and range. Choose any two points from the data using
different independent variables and use those two points to
determine the rate of change (slope). Then, using the dependent
data value of -500 as your initial value, write an equation for the
linear function model. Predict what you expect at a height of
75".

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,...
