Atechnician compares repair costs for two types of microwave ovens (type i and type ii). he believes that the repair cost for type i ovens is greater than the repair cost for type ii ovens. a sample of 60 type i ovens has a mean repair cost of $⁢85.79, with a standard deviation of $⁢15.13. a sample of 56 type ii ovens has a mean repair cost of $78.67, with a standard deviation of $⁢17.84. conduct a hypothesis test of the technician's claim at the 0.1 level of significance. let μ1 be the true mean repair cost for type i ovens and μ2 be the true mean repair cost for type ii ovens. step 1 of 4: state the null and alternative hypotheses for the test. step 2 of 4: compute the value of the test statistic. round your answer to two decimal places. step 3 of 4: determine the decision rule for rejecting the null hypothesis h0. round the numerical portion of your answer to three decimal places. step 4 of 4: make the decision for the hypothesis test. reject or fail to reject null hypothesis

Since p value <0.1 accept the claim that oven I repair costs are more

Step-by-step explanation:

The data given for two types of ovens are summarised below:

Group   Group One     Group Two  

Mean85.790078.6700

SD15.130017.8400

SEM1.95332.3840

N60      56      

Alpha = 10%

(Right tailed test)

The mean of Group One minus Group Two equals 7.1200

df = 114

 standard error of difference = 3.065

 t = 2.3234

p value = 0.0219

If p value <0.10 reject null hypothesis

4) Since p value <0.1 accept the claim that oven I repair costs are more

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
