Two sample summary hypothesis test. Consider a random sample of 14 M&M'S. Each weighed 2.5, 2.1, 2.7, 2.3, 3.0, 2.4 and 2.7. And the remaining 7 plain M&M'S weighed 08, 0.9, 0.8, 0.7, 0.9, and 0.6.

Answer #1

The hypothesis being tested is:

H0: µ1 = µ2

H1: µ1 ≠ µ2

Group 1 Group 2
2.529 0.783 mean
0.298 0.117 std. dev.
7 6 n
8 df
1.7452 difference (Group 1 - Group 2)
0.1225 standard error of difference
0 hypothesized difference
14.250 t
5.73E-07 p-value (two-tailed)

The p-value is 0.0000.

Since the p-value (0.0000) is less than the significance level (0.05), we can reject the null hypothesis.

Therefore, we can conclude that µ1 ≠ µ2.

A sociologist claims that children spent more time watching television in 1981 than children do today. A study was conducted in 1981 to find the time that children watched television on weekdays. Recently, a similar study was conducted. The results of these studies (in hours per weekday) are shown below. Assume the population standard deviation is 0.8 for 1981 and 0.6 for today. At α=0.05, can you support the sociologist's claim? Complete parts (a) through (d) below. 1981 1981 2.5...

We wish to determine the impact of Specification Buying, X11, on Satisfaction Level, X10. To do so we will split the Hatco data file into two separate data sets based on the Specification Buying, X11. This variable has two categories: 1=employs total value analysis approach, evaluating each purchase separately; 0 = use of specification buying. Sort the entire Hatco data set based on Specification Buying. This will create two separate groups of records. Those records with X11 = 0 and...

Consider the following summary statistics, calculated from two independent random samples taken from normally distributed populations. Sample 1 x¯1=20.87 s21=2.01 n1=16 Sample 2 x¯2=24.00 s22=3.36 n2=15 Test the null hypothesis H0:μ1=μ2against the alternative hypothesis HA:μ1<μ2. a) Calculate the test statistic for the Welch Approximate t procedure. Round your response to at least 3 decimal places. b) The Welch-Satterthwaite approximation to the degrees of freedom is given by df = 26.366427. Using this information, determine the range in which the p-value...

Consider two independent random samples of sizes n1 = 14 and n2 = 10, taken from two normally distributed populations. The sample standard deviations are calculated to be s1= 2.32 and s2 = 6.74, and the sample means are x¯1=-10.1and x¯2=-2.19, respectively. Using this information, test the null hypothesis H0:μ1=μ2against the one-sided alternative HA:μ1<μ2, using the Welch Approximate t Procedure (i.e. assuming that the population variances are not equal). a) Calculate the value for the t test statistic. Round your...
