We can express the null and alternative hypothesis as:
It is assumed a significance level of 0.05.
The standard deviation of the difference of means is calculated as:
The test statistic is
The degrees of freedom are:
The P-value for t=10.11 is P=0, so it is smaller than the significance level. The null hypothesis is rejected.
We can conclude that male and female consumers differ in the amounts they spend.

Answer:
You inject 60.9628 milliliters of dosage
Step-by-step explanation:
1 pound = 0.453592kg,
Patient's weight in pounds = 168
Patient's weight in kg = 
Now we are given that The dosage is 0.4 mg per kilogram of bod
So, dosage = 
1 microgram = 0.001 mg
Concentration of drug = 
Now we are supposed to find How many milliliters (= cc) are you to inject?
So,milliliters of dosage required to inject = 
Hence you inject 60.9628 milliliters of dosage
