Answer:
At least two of the restaurant have different mean delivery time.
Step-by-step explanation:
The ANOVA known as Analysis of variance involves the hypothesis testing of means on the basis of variances. The null hypothesis in ANOVA is taken as the equality mean i.e. H0: All means are equal. Whereas alternative hypothesis consists of at least two means are not equal.
The problem states that a pizza lover is comparing average delivery time. The null and alternative hypothesis in this case would be
H0: All restaurant have equal mean delivery time.
H1: At least two restaurant have different mean delivery time.

Step-by-step explanation:
Answer:
Circumference: 64π
Ratio: 1 : 4
Measure of ∠xoy: π/2
Step-by-step explanation:
We are given an arc length of 16π. Since it's in terms of pi, we use the formula
S = rФ where r is the radius, and Ф is the measure of the angle in radians (in terms of pi)
We are given S = 16π and r = 32, plug those in and find Ф
16π = 32Ф
16π/32 = Ф
π/2 = Ф
This is the measure of the central angle.
The angle is π/2 radians. There are 2π radians in the circumference, so the circumference is 4 times the arc length created by the central angle. (There are 4 halves in 2) so the ratio of the arc length tothe circumference is 1 : 4
The formula for circumference is C = 2πr, where r is the radius, so we hace
C = 2π(32) = 64π
Answer:
Scatter plot graph, both 8 and 12 seem less likely to fit they are longer hours in the time axis x, but if we draw a straight line through 5hrs with a ruler, we see a mirror image of 4 to 6 and see less activity in larger amounts of higher hours spent between 7-12
