Plot the points in the grid below.

Clear All Draw: Dot

Using your calculator, run a linear regression to determine the
equation of the line of best fit. Round to two decimal places, use
x for the variable.

y=

Using your equation, estimate the mass of the object at 11
minutes.

grams

Answer #1

Dot plot:

Regression equation:y = -0.70x + 43.92

Using your equation, estimate the mass of the object at 11 minutes.

x = 11

y = -0.70*11 + 43.92 = 36.22 grams

A student recorded the speed of an object as a function of
time and obtained the following data:
Reading no. Time (s) Speed (m/s)
1 2.0 1.20
2 3.0 1.70
3 5.0 2.70
4 5.50 2.95
5 6.60 3.50
6 8.0 4.20
1) Prepare a sheet of graph paper for plotting Speed versus
time. You should make the speed on the vertical axis and the time
on the horizontal axis.
2) Plot the measured values on the speed-time graph.

EXPERIMENT #1: EGG OSMOSIS
STEP ONE:
Read the introduction in your lab manual on page
233-244.
Watch the video on blackboard entitled “Osmosis Lab
Procedure Video 1”
In this lab, decalcified eggs are placed into 4 separate
solutions of varying glucose concentrations. The eggs are meant to
simulate cells. Mass of the eggs will be recorded initially, and
then eggs will be placed into a beaker filled with one of the
following:
-Distilled Water
-0.5 M glucose
-1.5 M glucose...

A set of numbers such as those below is meaningless without some
background information. The INDIVIDUALS here are Newcomb's 66
repetitions of his experiment. We need to know exactly WHAT
VARIABLE he measured, and in WHAT UNITS. Newcomb measured the time
in seconds that a light signal took to pass from his laboratory on
the Potomac River to mirror at the base the Washington Monument an
back, a total distance of about 7400 meters. Just as you can
compute the...
