A variable contains five categories. It is expected that data areuniformly distributed across these five categories. To test this, asample of observed data is gathered on this variable resulting infrequencies of 27, 30, 29, 21, and 24. Using a = .01, the appropriatedecision is _____.do not reject the null hypothesis that the observeddistribution is not uniformO do not reject the null hypothesis that the observeddistribution is uniformO reject the null hypothesis that the observed distribution isuniformO do nothingO reject the null hypothesis that the observed distribution isnot uniform

Assume that hybridization experiments are conducted with peas having the property that for offspring, there is a 0.75 probability that a pea has green pods. Assume that the offspring peas are randomly selected in groups of 10. Complete parts (a) through (c) below. a. Find the mean and the standard deviation for the numbers of peas with green pods in the groups of 10. The value of the mean is u= | peas. (Type an integer or a decimal. Do not round.) The value of the standard deviation is o = peas. (Round to one decimal place as needed.) b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high. Values of peas or fewer are significantly low. (Round to one decimal place as needed.) Values of peas or greater are significantly high. (Round to one decimal place as needed.)
Twelve different video games showing alcohol use were observed. The duration times of alcohol use were recorded, with the times (seconds) listed below. What requirements must be satisfied to test the claim that the sample is from a population with a mean greater than 80 sec? Are the requirements all satisfied? 87 13 568 49 0 59 223 41 182 02 57 What requirements must be satisfied? Select all that apply. A. Either the population is normally distributed, or n > 30, or both. B. The conditions for a binomial distribution must be satisfied. C. At least one observation must be above or below 80 sec. D. The sample observations must be a simple random sample. Are the requirements all satisfied? OA. No. The sample size is not greater than 30, the sample does not appear to be from a normally distributed population, and there is not enough information given to determine whether the sample is a simple random sample. B. Yes. A normal quantile plot suggests that the sample is from a normally…

Assume that hybridization experiments are conducted with peas having the property that for offspring, there is a 0.75 probability that a pea has green pods. Assume that the offspring peas are randomly selected in groups of 12. Complete parts (a) through (c) below. a. Find the mean and the standard deviation for the numbers of peas with green pods in the groups of 12. The value of the mean is u= 9 peas. (Type an integer or a decimal. Do not round.) The value of the standard deviation is σ = 1.5 peas. (Round to one decimal place as needed.) b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high. Values of peas or fewer are significantly low. (Round to one decimal place as needed.)
Three randomly selected households are surveyed. The numbers of people in the households are 2 ,4 ,and 12. Assume that samples of size n equals 2 are randomly selected with replacement from the population of 2,4,and 12. Listed below are the nine different samples. a. Find the variance of each of the nine samples, then summarize the sampling distribution of the variances in the format of a table representing the probability distribution of the distinct variance values.
