Answer:
The null hypothesis can't be rejected.
Step-by-step explanation:
Given information:
Null hypothesis:
H₀ : π ≤ 0.70
Alternative hypothesis:
H₁ : π > 0.70
We need to check whether the null hypothesis is rejected or accepted.
If P-value < α, then we reject the null hypothesis H₀.
If P-value ≥ α, then we accept the null hypothesis H₀.
A sample of 100 observations revealed that p = 0.75 at the 0.05 significance level.
Here 0.75>0.05, it means p > α, therefore we can not reject the null hypothesis.
Answer:
a) 8.2 in^3 b) 25.8 in^3 c) 17.6 in^3
Step-by-step explanation:
volume of cone=(1/3)π(r^2)*h
a) 8.2 in^3
regular ice cream cone=(1/3)π(1.25^2)*5=8.18=8.2 in^3
b) 25.8 in^3
waffle cone=(1/3)π(1.875^2)*7=25.77=25.8 in^3
c) 17.6 in^3
waffle cone-regular ice cream cone= 25.8-8.2=17.6 in^3
Answer:
$618.95 rounded up. 0.004c
£388.09 on rent and $230.84 food
We can round up and state $619 to nearest tenth.
Or leave as non rounded Total $618.93
Step-by-step explanation:
27% of 1,437.40=388.09
1,437.40 - 388.09 = 1049.31
22% of 1049.31 = 230.8482
$230,84 Shown here, as not round up or down as 230.84 as £388.09 was not rounded up from 388.098.
= $618.95 rounded up. 0.004c
