There is a difference because in the spring, there may be more days of rain, therefore that would increase the mean for the spring compared to the other days.
for estimating round both the price of shoes and the percentage to round numbers
97.65 is close to 100, so use 100 for the price of shoes
68% is close to 70 so use 70%
then multiply 100 by 70 %,
100 *70% = 70 dollars
so Isaac would pay around 70 dollars
Answer:
- 6.547
Step-by-step explanation:
Given that:
Sample size (n) = 1207
p = 0.85
p0 = 0.92
The test statistic :
Z = (p - p0) / √(p0(1 - p0) / n)
Z = (0.85 - 0.92) / √(0.92(1 - 0.85) / 1207)
Z = - 0.07 / √(0.92(0.15) / 1207)
Z = - 0.07 / √0.0001143
Z = - 0.07 / 0.0106926
Z = - 6.5465446
Z = - 6.547
Larger = 2smaller + 1 ----(1)
smaller = 2 larger - 17 ----(2)
put (2) in (1)
larger = 2(2larger-17) + 1
larger = 4larger-34+1
-3larger = - 33
so larger= 11
then smaller= 2(11)-17 = 5
answer two integers are 11 and 5
A. 292.5
b. .65
c. 157.5
d. .35
