The two questions are:

1) A game is played with 4 fair, six-sided dice. A player rolls the 4 dice one after the other. If the first and last numbers are the same and the two middle numbers are the same, then a Yahtzee is scored (worth 50 points). Find the probability that a player scores a Yahtzee on his/her first play. *Round answer to 4 decimals

2) 32% of americans favor government spending for alternative fuel research. If a random sample of 11 americans is taken, answer the following:

i. what are the four conditions for this kind of probability experiment?

ii. in this experiment, what does the random variable X represent?

iii. find the probability that more than 1 person will favor government spending for alternative research. *round final answer to nearest 3 decimal places

iv. the mean, variance, and standard deviation of the number of americans that favor government spending for alternative fuel research

Thank you so much for your time and help! ]]>

I need to test whether this set of scores is at an above chance level where 0 indicates a chance level?

0.58

0.42

0.33

-0.02

0.44

0.62

0.89

Essentially there were 10 trials in my experiment where i was seeing if there was a discrimination preference between a novel and a familiar object. In trials 1-9 i didn't expect there to be (expected values = 0) but in trial 10 i expected them to prefer the novel object, therefore expected anything >0.

0.00 = no discrimination between the two

Positive number = preferred the novel object

Negative number = prefered the familiar object

I think I need to see if there's an effect of trial number on score (particularly if trial 10 is above chance/ significantly different to any of the other trials/ trials 1-9 combined if thats possible?), or if trials 1 through 9 are significantly different from 0?

on top of this, i had only 7 participants !!

no i guess id have to use non-parametric due to a small sample size?

Thank you so so so so so sooooooo much in advance if you help me out!

I'm using SPSS by the way.

The majority of them are negatively skewed so I know I have to reflect the data before I transform it – if the two groups have different maximum scores, do I use different maximums in the transformation formula or do I use the maximum overall?

E.g.

Group 1 – Maximum = 36

Group 2 – Maximum = 39

So do I do

A) log10(40-Var) – for both groups

B) log10(37-Var) – for Group 1, and log10(40-Var) for group 2

And if I am later going to calculate a composite score, do I need to use the same transformation for all of the scores?

There are also a couple of outcomes where the data is negatively skewed for one group and positively skewed for the other – how do I deal with this?

Any help would be massively appreciated :) ]]>
