7. Let us assume that what we want is to know whether the wines of the designation of origin have the same alcoholic content, as well as their variability in the same, as those of another designation of origin, for example Baja California. It is a question of whether there is a clear differentiation in these two regions, because of the geographical proximity of the two regions, it is possible that there will be fraud and that wines from both regions will be exchanged depending on the market. 2 samples are taken from different wines:

Sto. Tomas 12,8 12,8 12,5 11,9 12,5 12,1

Valle de Guadalupe 13,0 14,0 13,2 13,4 13,2 13,9

a) Build a confidence interval for the average alcohol content of Sto. Tomas wine.

b) Assuming a level of significance of 5 % Is it possible to assume that in wine 2 it has a higher alcohol content?

We want to know whether the proportion of U.S. children living in families with combined incomes below the poverty line has changed in the last 20 years. In 2000 the proportion of children living below the poverty line was 12%. Out of a recent random sample of 90 children 9 were from families with combined incomes below the poverty line. Use this information to answer the following. The alternative hypothesis for the above would be A. ☐μ = 12% B....

We want to know whether an independent variable (room temperature) affects scores on a dependent variable (ratings of anger). The levels of the IV are hot and cold and the DV is measured on an anger scale (ranging from 0 no anger to 10 high anger). A random sample of subjects has been taken from the universe. Half of the subjects are randomly placed in the hot room while the other half are placed in the cold room. The samples...

Suppose we want to test whether or not three means are equal. We want to perform this test with a 2% significance level. If we perform an ANOVA test, what is the probability of the test producing accurate results (avoiding a Type I error)? Suppose we, instead, run three separate hypothesis tests (t-tests), each with 2% significance level. Mean 1 = Mean 2 Mean 1 = Mean 3 Mean 2 = Mean 3 What is the probability that all three...
