- Gestation period is the length of pregnancy, or to be more precise, the interval between fertilization and birth. In Syrian hamsters, the average gestation period is 16 days. Suppose you have a sample of 31 Syrian hamsters who were exposed to high levels of the hormone progesterone when they were pups, and who have an average gestation length of 17.1 days and a sample variance of 26.0 days. You want to test the hypothesis that Syrian hamsters who were exposed to high levels of the hormone progesterone when they were pups have a different gestation length than all Syrian hamsters. Calculate the t statistic. To do this, you first need to calculate the estimated standard error. The estimated standard error is sMM= a. 31, b. 0.5232, c. 0.7328, d. 0.9158. The t statistic is- a. 1.50, b. 2.10, c. 2.63, d. 1.20 Now suppose you have a larger sample size n = 95. Calculate the estimated standard error and the t statistic for this sample with the same sample average and the same…Differentiate between bounded and unbounded distribution?ANOVA is based on an F-ratio that is calculated as the ratio of two variance estimates, the variance between groups and the variance within groups, but enables conclusions to be made about the means of the samples involved. What is the logic of that? I.e., explain the rationale that supports the use of variance estimates
- A parametrical statistical test is one that makes assumptions about the parameters that define the properties of the population distributions from which data is drawn.True or false?If sample variance were to be computed by dividing Ss by n,then the average value of the sample variances from all the possible random samples would consistently ____ the population variance. underestimate equal impossible to determine overestimateThere are instances where system error occurs which greatly affects the mechanics of the game. In the past, it was recorded that, on the average, one system error occurs in every 500 games. To know the chances of system error(s) occurring in Shawn’s game, poisson distribution should be used with average rate of occurrence equal to _____. With this, the probability that Shawn will experience no system error in the game is ____.
- The personality variable extraversion is normally distributed in the population and has a mean of 10 and a standard deviation of 2. Researchers consider individuals who are 1 standard deviation above the mean “highly” extroverted. What is the probability that you can randomly sample 3 people from the population and all 3 would be “highly” extroverted?How is it that estimates of variance can be used to test a hypothesis about means?A financial analyst wants to estimate the difference in the mean growth for all large- and small-cap stocks for the last 60 days. He selects a random sample of 30 large-cap stocks and 30 small-cap stocks from the large populations of large- and small-cap stocks. Are the conditions for constructing a 90% confidence interval for the difference in the true mean growth of all large- and small-cap stocks for the last 60 days met? Random: 10%: Normal/Large Sample:
- The patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.7 days and a standard deviation of 2.3 days.What is the probability of spending more than 4 days in recovery?The life span of a certain wood cutting machine manufactured by a factory has a normal distribution with a guarantee that any machine that stars malfunctioning within 36 months of the purchase will be replaced by a new one. How many percentages of machines are expected to be replaced in the following cases? Mean of 60 months and variance of 64 months2 Mean of 45 months and variance of 36 months2 Mean of 75 months and variance of 16 months2How do I make an observation about the nature of a distribution based on measures of central tendency and measures of variability? Ex: Central tendency - mean is 100.5, median is 101, and mode is 100. Variabilty - range is 70, variance is 256.76, and standard deviation is 16.02. Using these measures, make one observation regarding the nature of the distribution.
