Practice with p-values Work through these problems with your computer partner and/or instructor. Answers follow the problem set. 1. Suppose we’ve done the computation of the Z test statistic. For each of the following situations determine the p-value that goes along with Z. a. Z = 2.12‚ two-sided test b. Z = 4.55‚ two-sided test c. Z = -1.40‚ lower-tail test 2. Suppose Z = 1.92.Which has a smaller p-value‚ the upper-tail test or the two-sided test? From this‚ is it more likely to have a

1. Problem: Does age (grade) or gender influence the results of reading correctly a paragraph consisting of words with jumbled text? 2. Hypothesis: My hypothesis is that most of the higher age (grade) group and girls would correctly read a paragraph of words with jumbled text. I believe that this is because with age our brain develops to make up words faster even if the words have letters with jumbled text. Also‚ I think that the girls would give a better response in the experiment as they

of others‚ our decisions and actions tend to be the reflection of society whether they be positive or negative‚ rather than of our own creation.

Doppler effect The Doppler effect‚ named after Christian Doppler‚ is the change in frequency and wavelength of a wave as perceived by an observer moving relative to the source of the waves. For waves that propagate in a wave medium‚ such as sound waves‚ the velocity of the observer and of the source are relative to the medium in which the waves are transmitted. The total Doppler effect may therefore result from motion of the source‚ motion of the observer‚ or motion of the medium. Each of these

Effects of Agriculture on the Environment Introduction: Agriculture has changed dramatically‚ especially since the end of World War II. Food and fibre productivity rose due to new technologies‚ mechanization‚ increased chemical use‚ specialization and government policies that favoured maximizing production. These changes allowed fewer farmers with reduced labour demands to produce the majority of the food and fibre. Humans‚ like all other species‚ exploit their surroundings for the resources they

We wanted to extract‚ see and analyze DNA from a single strawberry( 12.11 g). The long‚ thick fibers of DNA store the information for the functioning of the chemistry of life. DNA is present in every cell of plants and animals. The DNA found in strawberry cells can be extracted using common‚ everyday materials. To start the procedure we needed the following supplies; one strawberry‚ one plastic cup‚ 10 ml of Cell Lysis Buffer (10% detergent‚ 1% NaCl)‚ one plastic zip-lock bag‚ one coffee filter‚
