<span>11.2 Florida voters. Florida played a key role in the 2000 and 2004 presidential elections. Voter registration records in August 2010 show that 41% of Florida voters are registered as Democrats and 36% as Republicans. (Most of the others did not choose a party.) To test a random digit dialing device that you plan to use to poll voters for the 2010 Senate elections, you use it to call 250 randomly chosen residential telephones in Florida. Of the registered voters contacted, 34% are registered Democrats. Is each of the boldface numbers a parameter or a statistic? Answer 41 % of registered voters are Democrats: parameter 36% of registered voters are Republicans: parameter 34% of voters contacted are Democrats: statistic 11.7 Generating a sampling distribution. Let’s illustrate the idea of a sampling distribution in the case of a very small sample from a very small population. The population is the scores of 10 students on an exam: The parameter of interest is the mean score μ in this population. The sample is an SRS of size n = 4 drawn from the population. Because the students are labeled 0 to 9, a single random digit from Table B chooses one student for the sample. (a) Find the mean of the 10 scores in the population. This is the population mean μ. (b) Use the first digits in row 116 of Table B to draw an SRS of size 4 from this population. What are the four scores in your sample? What is their mean ? This statistic is an estimate of μ. (c) Repeat this process 9 more times, using the first digits in rows 117 to 125 of Table B. Make a histogram of the 10 values of . You are constructing the sampling distribution of . Is the center of your histogram close to μ? Answer (a) μ = 694/10 = 69.4. (b) The table below shows the results for line 116. Note that we need to choose 5 digits because the digit 4 appears twice. (c) The results for the other lines are in the table; the histogram is shown after the table.</span>

6) How does an offspring of a mushroom or mold (asexual reproduction) compare to its parent?
Verizon [17]

A mushroom or a mold commonly reproduces asexually by the formation of spores. Spores are produced in the sporangium through mitosis involving only one parent. They are released from the parent and germinate into new a mushroom or a mold. The offspring are genetically identical to that parent because their formation do not involve meiosis and fertilization. Spores allow fungi to expand their distribution and colonize new environments.

which molecules are produced in glycolysis and used in fermentation? a. acetyl-coa and nadh b. lactate, atp, and c. glucose, atp
tangare [24]

c. Glucose and ATP are produced in glycolysis and used in fermentation.

Glycolysis is the process of breaking down glucose to produce energy. It generates two pyruvate molecules, ATP, NADH, and water. The process occurs in a cell's cytoplasm and does not require oxygen. It can be found in aerobic and anaerobic organisms.

Glycolysis is a cytoplasmic pathway that converts glucose into two three-carbon compounds while producing energy. Phosphorylation traps glucose with the help of the enzyme hexokinase.

Fermentation is a metabolic process that involves the action of enzymes to produce chemical changes in organic substrates. It is narrowly defined in biochemistry as the extraction of energy from carbohydrates in the absence of oxygen. Fermentation is an ancient method of food preservation. The method is still used today to make wine, cheese, sauerkraut, yogurt, and kombucha.

Which of the drugs (if either) was more successful in preventing the recurrence of depression relative to the placebo?
Alex17521 [72]
The results clearly reveal that Imipramine is by far more effective than Lithium in preventing the recurrence of depression. 62.16% of the patients taking Lithium had a recurrence of depression which is more than twice that of patients who took Imipramine (28.95%). 

The results also question the effectiveness of Lithium in general since the percentage of patients who had a recurrence of depression in the Placebo group (67.65%) is only slightly higher than that of the Lithium group (62.16%).
