Answer:
Step 1 t = - 2.552

Step 3 two values t = - 2.12 on the left and t = 2.12 on the right
Step-by-step explanation:
Normal Distribution

Table to use t-student table
a) left-tailed test α = 0,01 n = 19 gl = 19 -1 gl = 18
Directly from t table
t = - 2.552
b) Right-tailed test α = 0,1 n = 13 gl = 13 - 1 gl =12
Directly from t table
t = 1.356
c) Two-tailed test α = 0,05 but two tails means we use α/2
α/2 = 0,025 n = 17 gl = n - 1 gl = 17 -1 gl = 16
From table:
t = - 2.12 on the left tail and t = 2.12 on the right tail

Answer: do you do f4f?
Step-by-step explanation:
I think you want to convert it all to feet.
1 mile = 5,280 feet
2 miles = 5,280 × 2
5,280 × 2 = 10,560 feet
10,560 + 500 = 11,060 feet
2 miles and 500 feet is equal to 11,060 feet
Answer: 6.25 yards
Step-by-step explanation:
75 inches = 4 bows
To get 12, you have to multiply 4 by 3. Therefore, you also have to multiply 75 by 3.
75*3 is 225.
225 inches = 12 bows
225 inches is 6.25 yards. Hope this helps :)
