A sample of 100 information systems managers had an average hourly income of $40.00 with a standard deviation of $8.00. If we wa

Sedbober [7]

Answer:

The t-score is 1.96

Step-by-step explanation:

The margin of error is given as

(Margin of Error) = (critical value) × (standard deviation of the sample mean)

The critical value is usually obtained from the t-score or the z-score at the given confidence level.

With small sample sizes (sample sizes less than 30) and/or information about the population standard deviation is not known, the t-distribution is used to find critical values.

We convert the confidence level to significance level and use the sample size to trace out the t-score.

Significance level = (1 - confidence level)/2

For example, a confidence level of 95% mean that 5% (spread equally at the top and bottom of the distribution as 2.5% and 2.5%) is still room for error, hence, the significance level = (5%/2) = 2.5%

This information, with the sample size, directs one exactly to where to obtain the t-score for the distribution on the t-score table.

But, with large sample sizes, with known information about its standard deviation, we typically use critical values on the Z-distribution to obtain the margin of error.

And as the sample size increases, the t-score approximates the z-score.

So, for a sample size of 100, the t-score can be simply obtained from the z-score table for a confidence level of 95%; and that is 1.96.

Hope this Helps!!!

Beckett purchase the diamond ring in 2012 for $12,000 if the value of the rain increases by 32% each year what will the ring be

Brums [2.3K]

Answer:

$119520

Step-by-step explanation:

Given: Purchase price of Diamond ring= $12000

Value of ring increase by 32% each year.

First finding number of year between 2012 and 2040, to know the time period of value appreciation.

Time period= $2040-2012= 28\ years$

∴ Time period of value appreciation is 28 years.

Now, finding the value of diamond ring increased after 28 years.

Value of ring increased after 28 years= $\frac{12000\times 32\times 28}{100}$

∴ Increased value of diamond ring after 28 years= $107520

Next, Value of diamond ring after 28 years= $12000+107520= \$ 119520$

Hence, value of diamond ring in 2040 is $119520
