Researchers examined the effect of phosphate supplementation on bone formation in six healthy adult dogs. For each dog, bone formation was measured twice: once after 12 weeks of phosphate supplementation and once after a 12-week control period. The results in percent bone growth per year are shown below. Does the data provide evidence that phosphate supplementation significantly stimulates bone formation at 1% significance level? (Follow the 5-step)

Dog: 1 2 3 4 5 6
Control: 1.73 3.37 3.59 2.05 1.86 3.6
Phosphate: 8.16 4.58 3.98 5.24 3.04 7.03

1. Stating the null hypothesis (H0) and alternative (Ha)

2. Choosing a significance level ?

3. Calculating test statistic value t0

4. Calculate P-value using t-Table or software

5. Compare P-value and significance level ? and make a conclusion.

The effect of phosphate supplementation on bone formation was assessed in six healthy adult dogs. For each dog, bone formation was measured for a 12-week period of phosphate supplementation as well as for a 12-week control period.

Some researchers tested whether arthritis in dogs could be improved by supplementation with antioxidants and/or an aminosugar mixture (containing glucosamine and chondroitin). They gave combinations of these supplements (each a factor with two levels: treatment and control) to equal numbers of test subjects in a balanced factorial design. They tested the effects of these supplements on levels of inflammation using a factorial ANOVA. The ANOVA table from their output is copied below.                                                                                > model<-aov(inflammation~as.factor(antioxidant)*as.factor(aminosugar)) > anova(model) Df SS MS...

A study was conducted concerning the effect of calcium supplementation on bone loss among postmenopausal women. Women were randomized to 3 groups: estrogen cream and calcium placebo (n=15), placebo estrogen cream and 2000 mg/day of calcium (n=15), or placebo estrogen cream and calcium placebo (n=13). Subjects were seen every 3 months for a 2-year period. The rate of bone loss was computed for each woman and expressed as a percentage of the initial bone mass. The mean (+/- 1 sd)...

A. Researchers examined the relationship between cola consumption and bone loss after fifty. One thousand women were randomly sampled, everyone's cola consumption was recorded over a two month period of time, and bone density measures were also recorded. Researchers found that the more cola consumed, the lower the level of bone density. They concluded that cola consumption leads to loss of bone density. What type of study is this research and why? Identify the variables. Evaluation the internal validity. B....
