- A genetics engineer was attempting to cross a tiger and a cheetah. She predicted a phenotypic outcome of the traits she was observing to be in the following ratio: 4 stripes only: 3 spots only: 9 both stripes and spots. When the cross was performed and she counted the individuals she found 50 with stripes only, 41 with spots only and 85 with both. According to the Chi-square test, did she get the predicted outcome?A randomized experiment measured weight gain (in grams) of makes rats under six diets varyingby source of protein (beef, cereal, pork) and level of protein (low, high). Ten rats were assignedto each diet. Outline the design.Can we please run a paired samples t-test for this problem? Can I see the data output?
- (Please explain what I was doing wrong)Three adhesives are being analysed for their impact on the bonding strength of paper in a pulp and paper mill. The adhesives are each randomly applied to four batches. The data is shown in Table 2. Here, the three treatments are the adhesives (p=3) and the number of replications for each treatment is 4 (r=4). Is there a difference among the adhesives in terms of the mean bonding strength? Test at the 5% significance level. Given F0.05,2,9 = 4.26 Adhesive Bonding strength (kg) type Adhesive 1 10.2 11.8 Adhesive 2 12.8 14.7 Adhesive 3 7.2 9.8 Table 2 Bonding strength data 9.6 13.3 8.7 12.4 15.4 9.2How do you find the Homogeneity of Variance met?

- A medical student at a community college in city Q wants to study the factors affecting the systolic blood pressure of a person (Y) Generally, the systolic blood pressure depends on the BMI of a person (B) and the age of the person A. She wants to test whether or not the BMI has a significant effect on the systolic blood pressure, keeping the age of the person constant. For her study, she collects a random sample of 125 patients from the city and estimates the following regression function: Y= 15.50 + 0..90B+1.15A. (0.55) (0 40) The test statistic of the study the student wants to conduct (Ho: B, = 0 vs. H, B, #0), keeping other variables constant is. (Round your answer to two decimal places.) At the 5% significance level, the student will ▼ the null hypothesis. Keeping BMIl constant, she now wants to test whether the age of a person (A) has no significant effect or a positive effect on the person's systolic blood pressure. So, the test statistic associated with the one-sided test the…A laboratory has two large format printers installed. During the installation, the manufacturer has stated that the capacity of the printer is to print 20 maps of A4 size in an hour. Owing to various factors such as different students working on the printers, raw materials etc., there is a variation in the number of prints produced per hour. A researcher has taken a random sample of prints produced in 10 hours for printer 1 and 13 hours for printer 2, respectively. The following data gives the number of prints produced on a sampled hour by the two printers:Printer 1 18 19 19 18 17 19 18 19 18 19Printer 2 16 17 17 17 16 18 16 16 17 17 16 16 17Can the researcher ascertain that the variance is from the same population (i.e., population variances are equal)? Consider α = 0.05 as the significance level.2 students applied 2 different methods to determine the content of melamine in milk. The variance of the melamine content obtained by student A is 6.5 with 11 samples. The variance of the results by student B is 4.3 with 6 samples. Are these 2 methods different from each other? Select one: a. F = 0.66 < Fcrit, there is significant difference b. F = 0.66 < Fcrit, there is no significant difference c. F = 1.51 < Fcrit, there is significant difference d. F = 1.51 < Fcrit, there is no significant difference
- pls also find p valueA genetic expert was attempting to cross a tiger and a cheetah. She predicted a phenotypic outcome of the trait she was observing to be in the following ratio 4stripes:3spots:9 both stripes and spots. When the crossbreed was performed and she wanted the individual, she found 50 with stripes and only 41 with spots and 85 with both stripes and spots. Using the chi-square test confirm or reject predicted outcome given that the alpha level is equal to 0.05A two-way ANOVA experiment with interaction was conducted. Factor A had three levels (columns), factor B had five levels (rows), and six observations were obtained for each combination. Assume normality in the underlying populations. The results include the following sum of squares terms: SST=1542 SSA= 1042 SSB = 358 SSAB = 39 a. Construct an ANOVA table. (Round "MS" to 4 decimal places and "F" to 3 decimal places.)
