Carry out a one-way ANOVA by hand to test the following research question: Carl wants to know if drinking beer (2, 5 or 8 beers) affects the number of times people sing karaoke  at a local bar in a given night. He is predicting that the groups will differ significantly (α = .05). (Perform post-hoc tests if necessary)

A study was designed to compare the attitudes of two groups of nursing students towards computers. Group 1 had previously taken a statistical methods course that involved significant computer interaction. Group 2 had taken a statistic methods course that did not use computers. The students' attitudes were measured by administering the Computer Anxiety Rating Scale (CARS). A random sample of 10 nursing students from Group 1 resulted in a mean score of 55.9 with a standard deviation of 5.4. A random sample of 14 nursing students from Group 2 resulted in a mean score of 64.5 with a standard deviation of 5.7. Can you conclude that the mean score for Group 1 is significantly lower than the mean score for Group 2? Let μ1 represent the mean score for Group 1 and μ2 represent the mean score for Group 2. Use a significance level of α=0.05 for the test. Assume that the population variances are equal and that the two populations are normally distributed. Step 2 of 4 : Compute the value of the t test statistic. Round your answer to three decimal places. Step 3 of 4: Determine the decision rule for rejecting the null hypothesis H0. Round your answer to three decimal places. Step 4 of 4: State the test's conclusion. A. Reject Null Hypothesis B. Fail to Reject Null Hypothesis

A machine costing $213,200 with a four-year life and an estimated $16,000 salvage value is installed in Luther Company’s factory on January 1. The factory manager estimates the machine will produce 493,000 units of product during its life. It actually produces the following units: 122,600 in Year 1, 122,500 in Year 2, 120,100 in Year 3, 137,800 in Year 4. The total number of units produced by the end of Year 4 exceeds the original estimate—this difference was not predicted. (The machine cannot be depreciated below its estimated salvage value.)

Required:

Compute depreciation for each year (and total depreciation of all years combined) for the machine under each depreciation method. (Round your per unit depreciation to 2 decimal places. Round your answers to the nearest whole dollar.)

Compute depreciation for each year (and total depreciation of all years combined) for the machine under the Straight-line depreciation.

Compute depreciation for each year (and total depreciation of all years combined) for the machine under the Units of production.

Compute depreciation for each year (and total depreciation of all years combined) for the machine under the Double-declining-balance.

1) At which point along the titration curve of a weak acid titrated with a strong base does the pH = pK_a

- At the half equivalence volume

- At the equilavence volume

- Before any base is added

- Beyond equilavence volume

2) In a titration of a 100.0mL 1.00M HA weak acid solution with 1.00M NaOH, what is the pH of the solution after the addition of 131 mL of NaOH?   K_a = 1.80 x 10^-5 for HA. (3 significant figures)
