After taking a sample of 300 rice plants, you find the frequency of the betainealdehyde dehydrogenase gene (BADH2) allele conferring aroma to rice grains such asbasmati or jasmine to be 93 (out of 600 alleles total), leading to an estimated meanproportion of 0.15 with 95% confidence interval of 0.13, 0.19. Which of the followingstatements is correct regarding this CI?There is a 95% probability the true population proportion lies between 0.13 and0.19.There is a 95% probability the true population proportion includes 0.13 and 0.19.The 99.99% confidence interval would be closer to the true value.There is a 95% probability the interval between 0.13 and 0.19 contains the truepopulation proportion.The true population proportion lies between 0 and 1, but between 0.13 and 0.19there is higher probability of truth.

Sample size n = 600 We have given that the frequency of the betaine aldehyde dehydrogenase gene…

What are the hypotheses for testing to see if a correlation is statistically significant? Hor=0: H₁r0 Ho: p=0: H₁p0 Ho: p= ±1: H₁p #±1 Ho: p = 0; H₁:p=1 Ho: r = ±1; H₁: r#±1
A random sample of 15 observations of house price and house size reveals a correlation coefficient of negative 46. The null and alternative hypotheses are given as the following (rho is population's correlation coefficient) : H0: rho ≥ 0 H1: rho < 0 Using 5% significance level, find the critical value
A study is conducted involving 15 patients to investigate the relationship between their age and systolic blood pressure. Is the relationship between age and systolic blood pressure negative using Pearson correlation coefficient? yes or no or cannot be determined What is the strength of correlation between age and systolic blood pressure? weak, moderate, strong, or very strong If the tabulated value of r is equal to 0.514 at αα=0.05, what is the decision using Pearson r correlation? accept or reject Ho
A sample of 28 elements is selected to estimate a 95% confidence interval for the variance of the population. What is the chi-square values to be used for this interval?
A company produces 1,000 blue crayons every day. A sample of 50 crayons are analyzed, and 3 of them are found to not meet the standards of the company, so they are labeled defective. A simulation is run in which 50 crayons are chosen out of 1,000 so that each crayon chosen has a 6% chance of being defective. The simulation is run 500 times, and the mean proportion of defective crayons is 0.059 with a standard deviation of 0.012. What is a good margin of error based on this simulation? Based on a population proportion estimate and margin of error, is 0.07 a plausible value for the population proportion of crayons that are defective? Explain your reasoning.
A study was conducted to determine if lung cancer altered levels of surfactant in the alveoli of the lung. Seven healthy subjects in the study yielded the following data on surfactant levels: 18, 12, 15, 15, 16, 9, 17. Seven lung cancer patients yielded the following results: 16, 8, 7, 15, 11, 12, 9. Do these data indicate a difference in the surfactant level with cancer? Let α = 0.05. Give the p-value.
will this be sufficient or is not sufficient evidence.
What is the most accurate interpretation of a significant correlation of rs = -.55 between annual CO2 emissions and annual average temperature (ranked from hottest year to coldest year)? Increased CO2 emissions are associated with lower annual average temperature Increased CO2 emissions are associated with higher annual average temperature Increased CO2 emissions lead to higher annual average temperature Increased CO2 emissions lead to lower annual average temperature If we conducted a study with a small group of randomly selected first- year psychology students and found a Pearson’s r of -.39 between distance from home to university (measured in km) and class attendance, what could we say about the relationship in the population? University students who live far from their homes are less likely to attend class There is no relationship between distance between home and university with class attendance University students who live far from their homes are more likely to attend…
A statistical study is made to compare the % of smokers in small rural towns to the overall smoking rate of the US. Of 1500 asults selected randomly from small towns it is found that 285 of them smoke. With a cofidence interval of (017, 0.21). The CDC reports that 15.1% of all American adults smoke. Does the confidence interval suggest that smoking rate is higher in small towns than in the country overall?
You are conducting a study of three types of feed supplements for cattle to test their effectiveness in producing weight gain among calves whose feed includes one of the supplements. You have four groups of 30 calves (one is a control group receiving the usual feed, but no supplement). You will conduct a one-way ANOVA after one year to see if there are difference in the mean weight for the four groups. If SSbetween = 369.3 and SStotal = 945.1 for this data. Identify the SSwithin
A researcher hypothesizes that there is a positive correlation between the hours spent studying and the final exam score. They collect data from 20 students and compute the Pearson correlation coefficient, r, to be 0.75. Using a significance level of 0.05, test the hypothesis that there is a significant correlation between the hours spent studying and the final exam score.
