leo knows that each time a digit moves one place to the left in a whole number the value of the digit is 10 times as much. descr
Serga [27]

Answer:

Leo is true for any numbers (including decimal numbers)

Step-by-step explanation:

* Lets explain how to solve the problem

- In number 256

# 6 is the unit digit (one digit)

# 5 is the ten digit (10 digit)

# 2 is the hundred digit (100 digit)

- If we change the number to 2563

# 6 digit is moved 1 place to the left now its place changed from unit

  digit to ten digit (from 1 to 10) that means 6 in the second number

  is 10 times the 6 in the first number

# 5 digit is moved 1 place to the left now its place changed from ten

  digit to hundred digit (from 10 to 100) that means 5 in the second

  number is 10 times the 5 in the first number

# 2 digit is moved 1 place to the left now its place changed from  

  hundred digit to thousand digit (from 100 to 1000) that means 2

  in the second number is 10 times the 2 in the first number

- In number 2.345

# 2 is the unit digit (one digit)

# 3 is the tenth digit (1/10 digit)

# 4 is the hundredth digit (1/100 digit)

# 5 is the thousandth digit (1/1000 digit)

- If we change the number to 23.45

# 3 digit is moved 1 place to the left now its place changed from tenth

  digit to unit digit (from 1/10 to 1) that means 3 in the second number

  is 10 times the 3 in the first number

# 4 digit is moved 1 place to the left now its place changed from  

  hundredth digit to tenth digit (from 1/100 to 1/10) that means 4 in the

  second number is 10 times the 5 in the first number

# 5 digit is moved 1 place to the left now its place changed from  

  thousandth digit to hundredth digit (from 1/1000 to 1/100) that means

  5 in the second number is 10 times the 5 in the first number

∴ Leo is true for any numbers (including decimal numbers)

A study was conducted to measure the effectiveness of hypnotism in reducing pain. The measurements are centimeters on a pain sca
blondinia [14]

The confidence interval for mean of the "before-after" differences is \fbox{(-0.4037,1.8037)}

Further explanation:

Find the difference between the before pain and the after pain.

Difference = before-after

Kindly refer to the Table for the difference of between the before and after pain.

Sum of difference = 5.6

Total number of observation = 8

Mean of difference = 0.7

Sample standard deviation s = 1.3201

Level of significance = 5\%

Formula for confidence interval = \left( \bar{X} \pm t_{n-1, \frac{\alpha}{2}\%} \frac{s}{\sqrt{n}} \right)

confidence interval = \left( 0.7 \pm t_{8-1, \frac{5}{2}\%} \frac{1.3201}{\sqrt{8}} \right)

confidence interval = \left( 0.7 \pm t_{7, \frac{5}{2}\%} \frac{1.3201}{\sqrt{8}} \right)

From the t-table.

The value of t_{7, \frac{5}{2}\%=2.365

Confidence interval = ( 0.7 \pm 2.365}\times \frac{1.3201}{\sqrt{8}}) \right)

Confidence interval = \left( 0.7 - 2.365}\times \0.4667,0.7 + 2.365}\times \0.4667) \right

Confidence interval = (0.7-1.1037,0.7+1.1037)

Confidence interval = \fbox{(-0.4037,1.8037)}

The 95\% confidence interval tells us about that 95\% chances of the true mean or population mean lies in the interval.

Yes, the hypnotism appear to be effective in reducing pain as confidence interval include includes the positive deviation from the mean.
