For function

we have that

. This means that period of cosine function is π. Then from the formula for period

you obtain that

and b=2.
So, the function is

. If f(0)=4, then

and, respectively, a=4.

Answer:
H0 : μd = 0
H1 : μd > 0
Step-by-step explanation:
The scenario described above can be compared statistically using a paired test mean as the mean if the two groups are dependent, the two restaurants, Albuquerque and Santa Fe are both restaurant locations of a single restaurant company. Hence, to test the mean difference, we use the paired test statistic. Defined thus `
Null hypothesis ; H0 : μd = 0 and the Alternative hypothesis ; H1 : μd > 0
The nearest hundredth is 32.7
and the nearest ones place is 33
