Which is the correct equation for the chisquare statistic? Group of answer choices a)x^2 = [(observed-expected)^2]/expected b)x^2 = sum[((observed-expected)^2)/observed] c)x^2 = sum[((observed-expected)^2)/expected] d)x^2 = sum[(observed-expected)/expected] What is a "p-value"? Group of answer choices a)the threshold at which you will reject the null hypothesis b)the probability of the null hypothesis being false c) the percentage of days you are sick during the year d) the probability of the null hypothesis being true

How did P<0.005 come into being? How do you determine what is due to chance and what's not?

P₁ P₂ F₁ Population F2 BC₁ Variance 3.3 days² 4.7 days² 6.6 days² 19.2 days² 12.1 days² a) Given the variances from these specific populations, compute for the broad sense and the narrow sense heritability values. Express your final answers in percentage with one decimal place. Show complete solutions and box or highlight your final answers. cong

In a recently published case control study, the researcher reported an odds ratio of 3.55 (95% CI 1.88-5.4). This indicates that the OR is significant and the associated p=value is less than 0.05. A. TrueB. False     please explain the reasoning behind the answer, thank you!

Upon comparing the mass of Fuji apples grown on two farms in Georgetown, KY--one using organic fertilizer and a neighboring farm using commercial fertilizer, the a research program commissioned by the USDA finds that the mean mass of organically and commercially grown apples are 224.2 g and 224.6 g, respectively. The standard error for both means is 0.015 g. The statistical test obtained by comparing the mass of several thousand apples from each farm (organic: 6,000, commercial: 78,000) produced a p-value of 0.001. What is correct interpretation of the results? The apples from the non-organic apples tend to be heavier than organic apples. There is no discernible difference in the mass of apples grown on both farm; this is supported by the statistically significant P-vale of 0.001. O Apples from the commercial farm were heavier than those from the organic farm, and this difference is statistically significant. O The difference in mass of apples from the two farms is negligible.

I have a large number for my standard deviation. What does this tell me about the variability in my data? Select one: the variability is just right the variability is low the variability is high more data is needed

What does it mean when a correlation coefficient is negative? Canyou think of examples?

What are some general tips in calculating allele and genotype frequencies?   Examples of each will be useful.

What is the topic in statistics that is the most difficult ? Please be specific here. Saying “I don’t understand anything” or “I don’t understand module 7” are very vague and difficult for people to help with. Instead, try and narrow it down to something like “I am struggling computing Cohen’s d” or “I am struggling to determine whether we reject or fail to reject the null hypothesis.”

M 3 0²/12 Here, na (sum of squared differences), na - 1 is the number of moose sampled from the population with wolves absent. Estimate the variance in moose fat stores (WOLVES ABSENT). To do this, divide the Sum of squared differences by the sample size minus one (na-1). Enter this value in the bottom row of the left half of the table. Q4.10. Make sure you're on track. What is your estimated variance for fat stores with wolves absent? Check Answer
