With a sample size n=250. Use the pooled data to test whether the distribution of the percent wound healing is approximately normal. Specifically use the following distribution : 30%, 40%, 20% and 10% and =0.05 to run the appropriate test. We will be doing a goodness fit test. This is a categorical or ordinal outcome. Use the pooled data to test whether the distribution of the percent wound healing is approximately normal. How to do problem in EXCEL?

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
