What is the sum of 3/7, 4/5, and 2/3 round to two decimal places?​
Anna11 [10]

Answer:

1.90

Step-by-step explanation:

You would want to use a calculator since you need decimal places.

Once you type it into the calculator you should get 1.8952380952.

Since you're trying to simplify to the second decimal place, look at the third number after the decimal.

The 5 rounds up the 9 to a ten, which is represented by the 0.

That then turns the 8 into a nine.

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
