Suppose you are interested in studying whether scent affects spatial reasoning abilities. You decide to test spatial reasoning u

sing completion time scores for the paper-folding test with five people, repeating the test on each person with three different scents (cinnamon, lavender, and peppermint). In this experiment, the null hypothesis is that:
a. The completion time mean for at least one scent is different from another
b. There are no individual differences in the completion time means
c. There are no differences in the mean completion times among the scents compared
The factor of interest is the ___. and the dependent variable is the ___.

Answer: 1. c. There are no differences in the mean completion times among the scents compared

2. Scent; Completion Time

Explanation:

The Null Hypothesis of a research is that hypothesis which you aim to disprove because it holds that no significant relationship between the variables being researched exists.

In this scenario you are studying whether scent affects spatial reasoning abilities.

The Null Hypothesis will.be that which states that there is no relationship between scent and spartial reasoning therefore there will be no differences in the mean completion times among the scents compared.

The factor of interest is the variable that is being changed to examine a difference making it the SCENT in this scenario.

The dependent variable changes due to the Factor of Interest so it is the COMPLETION TIME.

Drying times for newly painted microwave oven cabinets are normally distributed with a mean of 2.5 minutes and a standard deviat
Marina86 [1]

Answer: 3.22

Explanation:

Given that;

mean = 2.5 min

standard deviation = 0.25 min

now to get the value of X required, we say

z = (x - u) / a

where z is the distance from the mean measured in the standard deviation units, x is the value we are interested in, u is the mean distribution, a is the standard deviation of the distribution.

the time delay should be just enough to allow 99.8% of the cabinets to dry completely = 99.8/100 = 0.9980

first we determine an appropriate z value.

Using the standardized normal tables,

value of z for approximately 0.9980 is 2.88

so using our initial equation z = (x - u) / a

we substitute the value

z = (x - u) / a

2.88 = ( x - 2.5) / 0.25

2.88 * 0.25 = x - 2.5

0.72 = x - 2.5

x = 0.72 + 2.5

x = 3.22
