- The column labeled “b” in Table 1 shows the slope for each of the allometric relationships between organ weight and body weight for reptiles, and the column to right shows the 95% confidence interval for the slope. According to the 95% confidence interval, which of these slopes is not significantly different from 1 (i.e. includes 1 in the confidence interval)? Which of the slopes are significantly different from 1? For the slopes that are significantly different from 1, does this slope indicate that the organ is growing at a faster or slower rate than the body?please quickly i will give you a thumb!For each example, choose the confidence interval that has a larger margin of error. 1) OA 90% confidence interval for a mean contructed from a sample of 55 OA 90% confidence interval for a mean contructed from a sample of 45 2) OA 90% confidence interval for a mean constructed from a sample of 45 OA 92% confidence interval for a mean constructed from a sample of 45 3) OA 90% confidence interval for a mean constructed from a sample of 45, using s OA 90% confidence interval for a mean constructed from a sample of 45, using o
- Come up with your own data for a problem that would ask for a 90% confidence interval utilizing Z. Clearly label your variables.I am looking for help on E and F. Thanks in advanceIf n = 20, the sample mean = 250, SD = 15, SEM = 3.354, what is the confidence interval (using 95% confidence level). What percent confidence do you have that the population mean is between what two values
- Step 2 (b) Which of the two intervals conveys more precise information about the value of the population proportion? Recall that a smaller standard error of results in a narrower confidence interval. A narrower confidence interval is then more precise. The width of Interval 1, (0.27, 0.35), is 0.35 0.27 = and the width of Interval 2, (0.30, 0.34), is 0.34 -0.30 = Submit Skip (you cannot come back) Therefore, --Select--- is the narrower and more precise interval.Suppose you are planning an experiment and a sample has yet been selected. For this experiment you plan on taking a SRS of 50 mice with pancreatic cancer measuring a particular hormone level. What would be the impact on a 95% confidence interval calculated from the experiment on these mice if instead of a SRS of 50 mice, a SRS of 200 mice were taken?A researcher investigated whether the temperature of milk, x, can be used to predict the milk's pH content, y. She predicted the pH level of a glass of milk with a temperature of 8.45 degrees to be ŷ= 6.795 a)A 95% confidence interval for the mean pH of all milk with temperature 8.45 degrees is calculated to be (6.76, 6.83). Which of the following is the correct interpretation of this confidence interval? -The mean pH level for all glasses of milk having a temperature of 8.45 degrees is somewhere between 6.76 and 6.83, with 95% confidence. -The pH level for one glass of milk with a temperature of 8.45 degrees is somewhere between 6.76 and 6.83, with 95% confidence. -There is a probability of 0.95 that the mean pH level for this glass of milk with temperature 8.45 degrees is between 6.76 and 6.83. -95% of all glasses of milk with a temperature of 8.45 degrees have a pH level between 6.76 and 6.83. b)Suppose we have a glass of milk whose temperature is 8.45 degrees. We…
