A dataset contains information identified with Research and development costs, all out resources of different organizations working in the semiconductor, substance, and energy enterprises. Both the Research and development costs and the complete resources are accounted for in huge number of dollars. The information table comprises of the accompanying sections: The characteristic logarithm of the Research and development cost, called LNRANDD; The regular logarithm of the all out resources, called LNTOTAL; A spurious variable for the synthetic business, called Substance**

19,20.A spurious variable for the energy business, called ENERGY. An analyst ran a direct relapse, utilizing LNRANDD as the reaction, and LNTOTAL, Substance, and ENERGY as indicators. The factual programming she utilized gave the accompanying assessed relapse condition: LNRANDD d = .02 + .1 LNT OT AL + .18 Synthetic .05 ENERGY

a. Gauge the Research and development cost for a compound organization which has absolute resources 540 million dollars.

b. Decipher the coefficient .1 in the above condition.

c. What is the surmised connection between the Research and development costs for an organization in the semiconductor business and the Research and development costs for an organization in the synthetic business, given that the two organizations have similar all out resources?

d. What is the estimated connection between the Research and development costs for an organization in the semiconductor business and the Research and development costs for an organization in the energy business, given that the two organizations have similar complete resources?

Leave x alone a persistent arbitrary variable that follows an ordinary dissemination with a mean of 200 and a

standard deviation of 51. Discover the estimation of x so the territory under the typical bend to one side of x is

around 0.3264. Adjusted to two decimal spot is

Before, the mean running time for a particular sort of spotlight battery has been 9.2 hours. The maker has presented an adjustment in the creation strategy and needs to play out a theory test to decide if the mean running time has expanded subsequently. The speculations are: HO : u=9.2 hours Ha : u> 9.2 hours where u is the mean running season of the new batteries Guess that the consequences of the inspecting lead to non-dismissal of the invalid theory. Order that determination as a Kind I mistake, a Sort ll blunder, or a right choice, if indeed the mean running time has expanded. Select one: O a. Type II blunder O b. Can't be resolved, inadequate data O c. Type | mistake d. Right choice

A wellbeing safety net provider has discovered that the "reasonable and customary" charge for a specific operation is $1200. They presume that the normal expense charged by one specific facility for this system is higher than $1200. The back up plan needs to play out a speculation test to decide if their doubt is right. Select one: O a. HO : [> $1200 Ha : = $1200 O b. HO : [= $1200 Ha : > $1200 O c. HO : [= $1200 Ha : < $1200 O d. HO : = $1200 Ha : > $1200 Utilize a table of t-qualities to appraise the P-an incentive for the predefined one-mean t-test. Left-followed test, n = 15, t =-2.627 Select one: O a. P < 0.005 O b. 0.01 < P < 0.025 O C. P > 0.005 O d. 0.005 < P < 0.01
