Simply plug -4 in for z in the equation. The result should give you T(z)=(-4)-6=-10
Notice -4 takes z spot
The worth of the collectible car in five years if its value is going up by 10% every year would be $46,704.79
<h3>What is the worth of the car?</h3>
If the value of the collectible car is increasing with time, it is said that the collectible car is appreciating in value.
The formula for calculating future value with appreciation:
FV = P (1 + r)^n
- FV = Future value
- P = Present value
- R = interest rate
- N = number of years
$29,000(1.1^5) = $46,704.79

Answer:
a
The null hypothesis is
The alternative hypothesis is
b

c
The decision rule is
Reject the null hypothesis
d
The conclusion is
There is no sufficient evidence to conclude that the variance of the immune response is equal to 1.9.
Step-by-step explanation:
From the question we are are told that
The variance is
The sample size is n = 30
The sample variance is
The level of significance is
The null hypothesis is
The alternative hypothesis is
Generally the test statistics is mathematically represented as

=> 
=> 
Generally from the degree of freedom is mathematically represented as

=> 
=> 
Generally from the chi distribution table the critical value of
at a degree of freedom of
is

=> 
Gnerally from the values obtained we see that
hence
The decision rule is
Reject the null hypothesis
The conclusion is
There is no sufficient evidence to conclude that the variance of the immune response is equal to 1.9.
