Answer:

so correct option is c. 1.51

Explanation:

given data

random sample n = 81

average speed x = 60 mph

standard deviation σ = 13.5 mph

interval estimate  μ =  86.9%

to find out

the value of the z

solution

we have given  μ =  86.9%

so we get here z critical value for the confidence level =  86.9 %

we will use here standard normal table

so z value for 86.9% is 1.51

so correct option is c. 1.51

weqwewe [10]

Answer:

Explanation:

As we know that time interest earned ratio = Income before interest and taxes / interest expense.

Sales                                                                                           = 546000

less: cost of goods sold                                                            =  (<u>244410</u>)

            Gross profit                                                                       301590

Less: <u>expenses</u>

          Depreciation expense                                                      =( <u>61900   </u>)    

         Profit before interest and taxes                                         239690

Less: tax

      (239690 * 23%)                                                                =   (<u>55128</u>)            

                         Profit                                                                   184562

Profit - Retained earning Addition  = Interest

      184562 - 74300 = 110262.

Interest earned ratio = 239690 / 110262 = 2.17 times
