The match probability rounded to six decimal places is:The Likelihood Ratio as a whole number (using the rounded number above in the equation) is:Which is the correct definition of the likelihood ratio?O A. There is a 1 in LR chance that a random person is the criminal.O B. There is a 1 in LR chance that the blood of a random person matches the blood at the crime scene at the loci THO1, TPOX, and CSF1PO.O C. There is a 1 in LR chance that the suspect is guilty.O D. There is a 1 in LR chance that the blood of the suspect matches the blood at the crime scene at the loci THO1, TPOX, and CSF1PO. Suppose that a crime scene DNA sample was recovered and a suspect was later arrested. The DNA profiles of the crime strain and the suspect were typed andboth had the same DNA profiles at loci THO1, TPOX and CSF1P0. If both had alleles 7 and 9 for THO1, alleles 11 and 12 for TPOX, and allele 12 for CSF1PO,compute the match probability and likelihood ratio using the chart below.

In a batch of 1000 machine screws, 15 are defective. A person randomly selects 20 screws, putting each screw back after each draw. For this set of screws: Calculate the variance of the number of screws that are defective. (use a decimal number, nearest to ten thousandth, such as 0.1234)
Let a be a random variable representing the percentage of protein content for early bloom alfalfa hay. The average percentage protein content of such early bloom alfalfa should be u = 17.2%. A farmer's co-op is thinking of buying a large amount of baled hay but suspects that the hay is from a later summer cutting with lower protein content. A small amount of hay was removed from each bale of a random sample of 50 bales. The average protein content from the samples was determined by a local agricultural college to be -15.8% with a sample standard deviation of S = 5.3%- At a = .05, does this hay have lower average protein content than the early bloom alfalfa?
A study of fox rabies in a country gave the following information about different regions and the occurrence of rabies in each region.

The manager of a company that assembles and exports a particular type of pumps wants to know if there is a link between the number of hours spent by assembly workers in training and their productivity on the job. A random sample of 7 assembly workers was selected and their performances evaluated. The summary of the obtained data is listed in Table 2.

Magnetic surveying is one technique used by archaeologists to determine anomalies arising from variations in magnetic susceptibility. Unusual changes in magnetic susceptibility might (or might not) indicate an important archaeological discovery. Let x be a random variable that represents a magnetic susceptibility (MS) reading for a randomly chosen site at an archaeological research location. A random sample of 120 sites gave the readings shown in the table below.

A random selection of volunteers at a research institute have been exposed to a typical cold virus. After they started to have cold symptoms, 15 of them were given multivitamin tablets formulated to fight cold symptoms. The remaining 15 volunteers were given placebo tablets. For each individual, the length of time taken to recover from the cold is recorded. At the end of the experiment the following data are obtained.

In Mendel's experiment, he obtained 724 plants with red flowers and 210 with white flowers in his cross of red flowered x white flowered pea plants. Is this result consistent with his hypothesis of factor segregation? Calculate the x and obtain the approximate value of P from Table 1, then interpret the results and clearly state your conclusion.

In a lightbulb factory, an administrator selects a random sample of bulbs produced on assembly line A and a random sample of bulbs produced on assembly line B. The administrator calculates the proportion of malfunctioning bulbs produced by each assembly line and finds that the difference between them (A - B) is 0.008. A researcher conducted a hypothesis test with the following hypotheses: H0: The proportion of malfunctioning bulbs from assembly line A is the sample as the proportion of malfunctioning bulbs from assembly line B. HA: The proportion of malfunctioning bulbs from assembly line A is greater than the proportion of malfunctioning bulbs from assembly line B. She found a P-value of 0.016. What is the best interpretation of this P-value? a If there is no difference in the proportions of all defective parts made on the two assembly lines, the probability of observing a difference of at least 0.008 is 0.016. b If there is a difference of 0.016 in the proportions…
