Answer:


Step-by-step explanation:
Given that A perfume company claims that the mean weight of ther new perfume is at least 8.9 fluid oz
For testing this claim, in Statistics we perform a certain measures called hypothesis testing.
For this first step is to create null and alternate hypothesis.
Normally null hypothesis would have some statistic = something
Here we want to test the mean weight of perfume
Hence null hypothesis would be
H0: mu = 8.9 fl oz.
Alternate hypothesis would be opposite of this claim
i.e.
Ha: mu ≠8.9 fluid oz
Hence answer is


Answer:
899 ft
Step-by-step explanation:
if point a is 400 feet from the base and 499 feet away from the top you would need to add 400+499 together to get 899
Answer:
59 patients
Step-by-step explanation:
Total patients Sam saw in a week = 236
Percentage of patients near-sighted = 25%
How many of the patients Sam saw were near-sighted?
Number of patients near-sighted = 25% of 236
= 25/100 × 236
= 0.25 × 236
= 59
Number of patients near-sighted = 59 patients
The number of patients Sam saw in a week that were near-sighted is 59 patients
