Answer:
am i supposed to do area? volume? circumfrence?
Answer:
p-value (0.0208) is less than alpha = 0.05 reject H0.
Step-by-step explanation:
we have the following data:
sample size = n = 75
x, the number to evaluate is 45
the sample proportion would be: x / n = 45/75
p * = 0.6
Now, the null and alternative hypotheses are:
H0: P = 0.72
Ha: P no 72
two tailed test
statistic tes = z = (p * - p) / [(p * (1-p) / n)] ^ (1/2)
replacing we have:
z = (0.6 - 0.72) / [(0.72 * (1-0.72) / 75)] ^ (1/2)
z = -2.31
p-vaule = 2 * p (z <-2.31)
using z table, we get:
p-vaule = 2 * (0.0104)
p-vaule = 0.0208
Therefore, p-value (0.0208) is less than alpha = 0.05 reject H0.
If you round 1.625 pounds to nearest hundredths its 1.63 pounds.
To solve, we subtract 20x from both sides and subtract 600 from both sides:
Then, we simplify by dividing both sides by 10:
Thomas and Ken have to work 20 weeks for their earnings to be the same
we know that
1 ft-------> is equal to 12 in
step 1
find the area of the walk
18 in wide--------> convert to ft
18/12=1.5 ft
area=1.5*32------> 48 ft²
step 2
find the cost at $2.10 a square foot
multiply 48 ft² by $2.10
48*2.1=$100.80
therefore
the answer is
$100.80
