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

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

During the winter of 2008-2009, the average utility bill for residents of a certain state was $184 per month. A random sample of 40 customers was selected during the winter of 2009-2010, and the average bill was found to be $174.91 with a sample standard deviation of $19.47 .Complete parts a and b below. a) Using alpha=0.05 ,does this sample provide enough evidence to conclude that the average utility bill in this state was lower in the winter of 2009-2010...
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...
