Create two different data sets such that a T test under the
assumption of equal variances will reject the null hypothesis, but
the T test under the assumption of unequal variances (Hint: Welch's
T statistic) will fail to reject the null hypothesis. Explain why
the two data sets fail to reject under unequal variance assumption
and why it rejects until equal variance assumption.

For the data below graph and determine the fit you should use
based on the information available. Also try to think about any
natural system that might use this type of fit (use
SciDavis). Let the horizontal axis represent time
in seconds. Choose a physical quantity for y data.
Paste graph below and list the values of fitting parameters,
along with their uncertainties. Watch significant figures and don’t
forget the units for each parameter.

Use the chi-square test for goodness of fit to determine if the
data shown below are consistent with an inheritance pattern of
simple dominance. Use p = 0.05 for determining
significance.
Cross: Aa x Aa
Offspring:

A. The data are consistent with a simple dominance pattern of
inheritance.
B. The data are not consistent with a simple dominance pattern
of inheritance.
