For letter C, which anova should i use? One way or two way without replication, please tell me. and show me an example and explain why Do this problem using Excel. The following data were obtained in calibrating acalcium ion electrode for the determination of pCa. A linear relationship between thepotential and pCa is known to exist.pCa = - log [Ca²*]E, mV5.00- 53.84.00- 27.73.00+ 2.72.00+ 31.91.00+ 65.1a. Plot the data and draw a line through the points by eye.b. Find the least-squares expression for the best straight line among the points. Plotthis line.c. Do an ANOVA and report the statistics given in the ANOVA table. Comment onthe meaning of the ANOVA statistics.d. Calculate the pCa of a serum solution in which the electrode potential was 15.3mV. Find the absolute and relative standard deviations for pCa if the result wasfrom a single voltage measurement.

Here we will use one way ANOVA because there is only one predictor variable. You donot have to…

A professor collected data from classes to see whether humans made selections randomly, as a random number generator would. Each of 36 students had to pick an integer from one to five. The data are summarized in the table below. A true random number generator would create roughly equal numbers of all five integers. Do a goodness-of-fit analysis to test the hypothesis that humans are not like random number generators. Use a significance level of a = 0.05, and assume these data were from a random sample of students. Click the icon to view the integer selection data. n Q A 1 Step 1: Hypothesize Ho: Humans are like random number generators and produce numbers in equal quantities. State the alternative hypothesis. Choose the correct answer below. @ HEF 2 W Z Since each expected count is, the condition that all the expected counts are 5 or more (Simplify your answer.)

An LED light bulb manufacturer claims that the average lifespan of its 60-watt LED light bulbs is 27,000 hours. A corporate watchdog group is suspicious of the company's claim and thinks that the true average lifespan of the 60- watt LED light bulbs produced by the company may be less than the advertised 27,000 hours. The group collected and tested a random sample of 211 light bulbs and found the average lifespan of the sample was 26,941 hours. Use the p-value method to test the hypothesis that the mean lifespan of this brand of 60-watt LED light bulb is less than 27,000 hours, using a = 0.1. Assume the standard deviation of the lifespan of all such light bulbs is known to be 370 hours. State the null and alternative hypothesis for this test. Ho: ? H₁: ? Determine if this test is left-tailed, right-tailed, or two- tailed. right-tailed two-tailed left-tailed Should the standard normal (z) distribution or Student's (t) distribution be used for this test? The Student's t distribution…
A worm in my apple-Codling moths are a devastating insect pest for apples. Each spring, adult moths lay their eggs on or around developing appies. When the eggs hatch the larva, or wom, tunnels into the apple, where they feed on the fruit and develop for three to five weeks. Cain has developed a scanning machine to detect the presence of larvae in appies. If the apple is infested with larvae, the machine reports a positive result 84.3% of the time. If the apple is not infested, the machine reports a negative result 64.6% of the time Round all answers to 4 decimal places 1. Suppose that 8.2% of apples in an orchard are infested with larvae. Assume a theoretical population of 10,000 apples and construct the contingency table for this scenario Test Negative Infested Not infested Total Test Positive 2. What proportion of apples will test positive for larvae infestation? 3. What proportion of apples that test positive for larvae infestation would we expect to not actually be infested with…
