(20 points) A statistics practitioner calculated the mean and the standard deviation from a sample of 400. They are x = 98 and s
Nimfa-mama [501]

Answer:

The P-value is 0.0234.

Step-by-step explanation:

We are given that a statistics practitioner calculated the mean and the standard deviation from a sample of 400. They are x = 98 and s = 20.

Let = population mean.

So, Null Hypothesis, : = 100 {means that the population mean is equal to 100}

Alternate Hypothesis, : > 100 {means that the population mean is more than 100}

The test statistics that will be used here is One-sample t-test statistics because we're yet to know about the population standard deviation;

T.S. = ~

where, = sample mean = 98

s = sample standard deviation = 20

n = sample size = 400

So, the test statistics = ~

= -2

The value of t-test statistics is -2.

Now, the P-value of the test statistics is given by;

P( < -2) = 0.0234 {using the t-table}

Select all the simplified expression <br>​
sineoko [7]

Answer:

1 / 3^5

1/ 243

Step-by-step explanation:

3^4 ÷ 3^9

We know that a^b ÷ a^c = a^ ( b-c)

3 ^ ( 4-9)

3^ -5

We can rewrite this as a^-b = 1/ a^b

1 / 3^5

We know that 3^5 = 243

1/ 243
