$1.45
1.50 times .05= 0.075
the sales tax was 0.075 cents, so if you subtract that from $1.50, you get the price before sales tax
Answer:
a) The test statistic is 
b) The pvalue is 0.0060.
Step-by-step explanation:
Question a:
Ha: pB < pNY
This means that the alternate hypothesis is rewritten as:

While the null hypothesis is:

The test statistic is:

In which X is the sample mean,
is the value tested at the null hypothesis and s is the standard error
pB = 0.581, pNY = 0.832
This means that 
0 is tested at the null hypothesis:
This means that 
Standard error = 0.1
This means that 
Test statistic:



The test statistic is 
Question b:
The pvalue is the probability of finding a proportion less than -0.251, that is, a difference of at least 0.251, which is the pvalue of Z = -2.51.
Looking at the z-table, Z = -2.51 has a pvalue of 0.0060
The pvalue is 0.0060.
Answer:
it’s 8 and 2 and 4 and 0
Step-by-step explanation:
this is because when you multiply 2x the x is an 8 so 2 times 8 is 16 then minus 2 is 14 which is greater than -4 same for my other answer
3 times 2 is 6 then you do 6 times 3 which is 18 +3 =21 you add them all up 21+6=27
