We wish to see if the dial indicating the oven temperature for a certain model oven is properly calibrated. four ovens of this model are selected at random. the dial on each is set to 300°f, and after one hour, the actual temperature of each is measured. the temperatures measured are 305°, 310°, 300°, and 305°. assume that the distribution of the actual temperatures for this model when the dial is set to 300° is normal. to test if the dial is properly calibrated, we will test the following hypotheses: h0: μ = 300 versus ha: μ ≠ 300. based on the data, what is the value of the one-sample t statistic? a. 4.90 b. 5.0 c. 2.45 d. 1.23

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
