A wildlife biologist is interested in comparing the mean number of miles flown per day by two types of birds when migrating over the ocean. Two independent samples of miles flown per day are collected with the following sample statistics. x1 =131.8, ₂2 =129.5, s₁ =10.3, s2 =11.5 The sample size for the first sample is n₁ =31 and the second sample has sample size n2 =36. Compute the test statistic for the following null and alternative hypotheses. Use two decimal place accuracy. Ho : μ1 = μ2 HA: 12

Question
A wildlife biologist is interested in comparing the mean
number of miles flown per day by two types of birds
when migrating over the ocean. Two independent
samples of miles flown per day are collected with the
following sample statistics.
x1 =131.8, X2 =129.5, s1 =10.3, s2 =11.5
The sample size for the first sample is n₁ =31 and the
second sample has sample size n₂ =36.
Compute the test statistic for the following null and
alternative hypotheses. Use two decimal place
accuracy.
Ho : μ1 = μ2
HA : μι < μ2
