A tissue can be 0.000075 meters thick.
Setler [38]

Answer:

The required expression is 7.5\times 10^5

Step-by-step explanation:

Consider the provided information.

A tissue can be 0.000075 meters thick and we need to represent it into scientific notation.

Steps to write a number in scientific notation.

  • Move the decimal place to the right so that the new number from 1 up to 10.
  • Determine the exponent, the exponent is the number of times you moved the decimal.

Now, consider the number 0.000075

Move the decimal point to 5 place right so that the new number from 1 up to 10.

Now, put the exponent the number of times you moved decimal. 7.5\times 10^5

Hence, the required expression is 7.5\times 10^5

disa [49]

Answer:

p value from chi square = 0.081

Step-by-step explanation:

Given that sociologists say the percentage of the classic music lovers is about 5%. From the survey, we know that only 83 out of 2000 people listen to the classic music. Let denote the proportion of the classic music lovers. The hypotheses are H0: p=0.05 vs Ha: p≠0.05

p value = 0.09

Instead of this if we do chi square

H0: Proportion of music lovers is 5% and non music lovers is 95%

Ha: Proportions are not as per the estimate

(Two tailed chi square test)

Observed       83           1917       2000

Expected        100          1900     2000

O-E                  -17              17          0

chi square

(O-E)^2/E        2.89         0.1521     3.0421

df =1

p value from chi square = 0.081

Though p value is not exactly the same, the conclusion in both tests are the same
