What would be the effect on Lybrand’s income if the special order were accepted? Lybrand’s income will increase or decrease by $ ____________   Lybrand Company is a leading manufacturer of sunglasses. One of Lybrand’s products protects the eyes from ultraviolet rays. An upscale sporting goods store has contacted Lybrand about purchasing 30,000 pairs of these sunglasses. Lybrand’s unit manufacturing cost, based on a full capacity of 250,000 units, is as follows: Direct materials $8   Direct labor 5   Manufacturing overhead (75% fixed) 24   Total manufacturing costs $37   Lybrand also incurs selling and administrative expenses of $75,000 plus $4 per pair for sales commissions. The company has plenty of excess manufacturing capacity to use in manufacturing the sunglasses. Lybrand’s normal price for these sunglasses is $45 per pair. The sporting goods store has offered to pay $32 per pair. Since the special order was initiated by the sporting goods store, no sales…

Q9: Please answer both parts  Dr. Nkrumah studies white-footed mice in the Konza Prairie in Kansas. Recently he has noticed that a new species of grass (martin grass) has appeared in one of his study areas. The seeds of this new plant seemed to be used by the mice as a food source and recent captures of mice in the area indicate that the mice in the area are increasing in overall weight. To determine if this new food source is causing the increase in mice weight Dr. Nkrumah has captured 60 mice from his site. He weighs each mouse and then places each into a separate cage. All the mice are kept in the same chamber, with the same light and temperture conditions. Half of the mice are given a diet consisting of entirely of wheat seeds (normal diet), and the other half are feed a diet that consist of 50% wheat seeds and 50% martin grass seeds.The volume of each diet is the same. He feeds the mice these diets for two weeks and then weighs each mouse. Identify the null and alternate…

Activating baking yeast To shorten the time it takes him to make his favorite pizza, a student designed an experi-ment to test the effect of sugar and milk on the activation times for baking yeast. Specifically, he tested four differ-ent recipes and measured how many seconds it took for the same amount of dough to rise to the top of a bowl. Herandomized the order of the recipes and replicated eachtreatment 4 times.Here are the boxplots of activation times from the fourrecipes: The ANOVA table follows: Source DFSum ofSquaresMeanSquare F-Ratio P-ValueRecipe 3 638967.69 212989 44.7392 60.0001Error 12 57128.25 4761Total 15 696095.94 a) State the hypotheses about the recipes (both numeri-cally and in words). b) Assuming that the assumptions for inference are satis-fied, perform the hypothesis test and state your conclu-sion. Be sure to state it in terms of activation times and recipes.c) Would it be appropriate to follow up this study withmultiple comparisons to see which recipes differ…

Survey: Reaction to Poison Ivy Allergic reactions to poison ivy can be miserable. Plant oils cause the reaction. Researchers at Allergy Institute did a study to determine the effects of washing the oil off within 5 minutes of exposure. A random sample of 1000 people with known allergies to poison ivy participated in the study. Oil from the poison ivy plant was rubbed on a patch of skin. For 500 of the subjects, it was washed off within 5 minutes. For the other 500 subjects, the oil was washed off after 5 minutes. The results are summarized in Table 5-5. Let’s use the following notation for the various events: W = washing oil off within 5 minute. A = washing oil off after 5 minutes. N = no reaction.M = mild reaction. S = strong reaction. Find the following probabilities for a person selected at random from this sample of 1000 subjects. (a) P (N) , P (M) , P (S)(b) P(N| W), P(S | W)(c) P (N | A) , P (S |A)(d) P(N and W), P (M and W)(e) . Are the events N = no reaction and M = mild…
