A researcher wants to study the average lifetime of a certain brand of light bulbs (in hours). In testing the hypotheses, H0:μ=950 hours vs. H1:μ≠950 hours, a random sample of 25 light bulbs is drawn from a normal population whose standard deviation is 200 hours. A) Calculate β, the probability of a Type II error when μ=1000 and α=0.10.B) Calculate the power of the test when μ=1000 and α=0.10.C) Interpret the meaning of the power of the test. D) Recalculate β if n is increased from 25 to 40.E) Review the results of the previous questions. What is the effect of increasing the sample size on the value of β?

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
