a) The test statistic is
nothing
.
(Round to two decimal places as needed.)
Determine the appropriate critical value(s).
The critical value(s) is(are)
nothing
.
(Round to
two
decimal places as needed. Use a comma to separate answers as needed.)
Since the test statistic
▼
falls
does not fall
in the rejection region,
▼
reject

Upper H 0
.
There is
▼
insufficient

evidence to conclude that the mean of population 1 is greater than the mean of population 2.
b) The p-value is

(Round to three decimal places as needed.)
Since the p-value is

Preliminary data analyses indicate that the assumptions for using pooled t-procedures are satisfied. Independent random samples of 104 plots with cropland and 98 plots with grassland yielded the given summary statistics for the number of species of bird. At the 55% significance level, do the data provide sufficient evidence to conclude that a difference exists in the mean number of species in the two regions? Cropland Grassland x overbar 1 equals 14.44 x overbar 2 equals 15.66 s 1 equals...
