Answer:
0≤y10
Step-by-step explanation:
Given the expresssion;
y = 10 - 0.05x
To get the range, we will first substitute for the value of y by substituting the value x =0
y = 10 - 0.05(0)
y = 10
Hence the required range of values falls between 0 and 10;
0≤y10

Answer:
Step-by-step explanation:
Data given and notation
n=1500 represent the random sample taken
estimated proportion of of chips fail in the first 100 hours
is the value that we want to test
represent the significance level
z would represent the statistic (variable of interest)
represent the p value (variable of interest)
Concepts and formulas to use
We need to conduct a hypothesis in order to test the claim that the actual percentage that fail is different from the stated percentage. Find the value of the test statistic.:
Null hypothesis:
Alternative hypothesis:
When we conduct a proportion test we need to use the z statisitc, and the is given by:
(1)
The One-Sample Proportion Test is used to assess whether a population proportion
is significantly different from a hypothesized value
.
Calculate the statistic
Since we have all the info requires we can replace in formula (1) like this:
we are given
Hao dog ate 40 cans of dog food in 31 days
it means that

Firstly, we will find for 1 day
we can divide both sides by 31


now, we can multiply both sides by 6


so,
Hao buy to feed his dog for for the next 6 days is 7.74194 cans.......Answer
