T- Test:
Seven tomato plants were treated with chlorogenic acid (and seven control plants were not treated) to determine if this acid influences the activity of the enzyme o-diphenol oxidase in their leaves which is normally 13 units. The enzyme activity data are presented below. Does this treatment affect enzyme activity?

Mendelian Genetics
In tomato plants, the gene R has two alleles that control fruit
color: the R allele is dominant and produces red tomatoes; the
r allele is recessive, and when homozygous produces yellow
tomatoes. Gene T controls plant height: the T allele is
dominant and produces tall plants; the t allele is
recessive and when homozygous produces dwarf plants. Genes R and T
undergo independent assortment.

RRTT and rrtt are crossed. What genotype...

In one of Sue's experiments, 500 plants were treated with a
chemical and 350 of them were found to have a plant disease. Use a
0.01 significance level to test the claim that the rate of plant
disease among all plants treated with the chemical is equal to
74%.
State the final conclusion.
Applicable answers:
The sample evidence does NOT support the rejection of the null
hypothesis claim that the rate of plant disease among all plants
treated with the...

A horticulturist is studying the relationship between tomato
plant height and fertilizer amount. Thirty tomato plants grown in
similar conditions were subjected to various amounts of fertilizer
over a four-month period, and then their heights were measured. The
results are shown in the accompanying table. Fertilizer Amount
(ounces) Tomato Plant Height (inches) 1.9 20.4 5.0 29.1 4.2 28.2
1.3 24.3 4.9 29.2 5.4 29.8 3.1 34.6 0.0 25.3 2.3 26.2 2.5 25.7 0.9

6. Tall tomato plants are produced by the dominant allele, D,
and dwarf plants by its recessive allele, d. Hairy stems are
produced by a dominant allele, H, and hairless stems by its
recessive allele, h. A dihybrid tall, hairy plant is test crossed.
The following F1 offspring were produced: 118 tall, hairy plants
121 dwarf, hairless plants 112 tall hairless plants 109 dwarf,
hairy plants

In a test of the effectiveness of garlic for lowering cholesterol, 40 subjects were treated with raw garlic. Cholesterol levels were measured before and after the treatment. The changes (before minus star) in the levels of LDL cholesterol (in mgdL) have a mean of 6 and a standard deviation of 16.8. Use a 0.01 significance level to test the claim that with garlic treatment, the mean change in LDL cholesterol is greater than 0. What do the results suggest about...

In a test of the effectiveness of garlic for lowering
cholesterol, 64 subjects were treated with raw garlic. Cholesterol
levels were measured before and after the treatment. The changes
(before minus after) in their levels of LDL cholesterol (in
mg/dL) have a mean of 0.2 and a standard deviation of 1.86. Use a
0.01 significance level to test the claim that with garlic
treatment, the mean change in LDL cholesterol is greater than
0.What do the results suggest about the...

In a test of the effectiveness of garlic for lowering
cholesterol, 49 subjects were treated with garlic in a processed
tablet form. Cholesterol levels were measured before and after the
treatment. The changes (beforeminusafter) in their levels of LDL
cholesterol (in mg/dL) have a mean of 2.7 and a standard deviation
of 16.8. Construct a 99% confidence interval estimate of the mean
net change in LDL cholesterol after the garlic treatment. What does
the confidence interval suggest about the effectiveness...

In a test of the effectiveness of garlic for lowering
cholesterol, 81 subjects were treated with raw garlic. Cholesterol
levels were measured before and after the treatment. The changes
(before minus after) in their levels of LDL cholesterol (in
mg/dL) have a mean of 0.9 and a standard deviation of 2.25 . Use a
0.10 significance level to test the claim that with garlic
treatment, the mean change in LDL cholesterol is greater than 0 .
What do the results...

In a test of the effectiveness of garlic for lowering
cholesterol, 45 subjects were treated with garlic in a processed
tablet form. Cholesterol levels were measured before and after the
treatment. The changes in their levels of LDL cholesterol (in
mg/dL) have a mean of 4.2 and a standard deviation of 19.6.
Answer the following (round as indicated).
A. What is the best point estimate of the population mean net
change in LDL cholesterol after the garlic treatment?
The best...
