Consider the accompanying data on breaking load (kg/25 mm width) for various fabrics in both an unabraded condition and an abrad

ed condition. Use the paired t test to test H0: ?D = 0 versus Ha: ?D > 0 at significance level 0.01. (Use ?D = ?U ? ?A.)
Fabric

1 2 3 4 5 6 7 8
U 36.3 55.0 51.2 38.6 43.2 48.8 25.6 49.6
A 28.5 20.0 46.0 34.0 36.5 52.5 26.5 46.5
State the rejection region(s). (If the critical region is one-sided, enter NONE for the unused region. Round your answers to three decimal places.)

t ? _______

t ? ________

Compute the test statistic value. (Round your answer to three decimal places.)

t = _____

State the conclusion in the problem context.

a.Reject H0. The data suggests a significant mean difference in breaking load for the two fabric load conditions.Fail to
b.reject H0. The data suggests a significant mean difference in breaking load for the two fabric load conditions.
c.Reject H0. The data does not suggest a significant mean difference in breaking load for the two fabric load conditions.

NEED HELP ASAP!!!
Sergeeva-Olga [200]

Answer:

(b) P(\textrm{Event of getting a 3 in the spinner)}  =  \frac{11}{61}

Step-by-step explanation:

Let E: Event of getting a 3 in the spinner.

So, the number of favorable outcomes  =  11

Total number of outcomes = Number of times the outcomes is {1,2,3,4,5,6}

= {13 +10 +11+16+11}  = { 61}

So, the total number of outcomes = 61

\textrm{Probability of Event E}  = \frac{\textrm{Number of favorable events}}{\textrm{Total number of outcomes}}

So, here P(\textrm{Event of getting a 3 in the spinner)}  =  \frac{11}{61}
