Well, for number three. You know that the length of the RECTANGULAR garden is 6.8 meters. Since it is a rectangle the garden will have 4 sides:two lengths and 2 widths. an easy way to find the width is to multiply the single length by 2, so 6.8 meters becomes 13.6. Then, you subtract that from the total perimeter, this leaves you with 7 meters. Those 7 meters are the sum of both width sides added together, so all you have to do is divide 7 by 2 to get 3.5 meters as your width. Before I go on do you understand how I got that number?

Find the P-value for the hypothesis test with a standardized test statistic z. Decide whether toreject the null hypothesis for t
iren2701 [21]

Answer:

1.) We don't reject the null

2.) We reject the Null

3.) We do not reject the null

Step-by-step explanation:

Obtaining p values using test statistic:

Given that ; we have a standardized test statistic and α - values ;

Let's define the decision region :

If Pvalue < α ; Reject H0 ; otherwise, fail to reject H0

A.)

Left tail , Z = - 1.32 ; α = 0.10

We can use the Pvalue calculator from Z score :

Pvalue = 0.934

Pvalue > α ; Hence, we fail to reject the null, H0

B.)

Right-tailed test, z = 2.46, α = 0.01

Pvalue from Zscore calculator ;

Pvalue = 0.0069

Pvalue < α ; Hence, we reject the null, H0

C.)

Two-tailed test, z = -1.68, α = 0.05

Pvalue from Zscore calculator ;

Pvalue = 0.093

Pvalue > α ; Hence, we fail to reject the null, H0
