The pooled variancce = 12
The pooled standard deviation = 12
The formula for Standard error using pooled standard deviation is
S E = S p 1 n 1 + 1 n 2 = 12 1 6 + 1 6 = 12 × 1 3 = 4 = 2
The formula for sample t-score is given by
t = x ¯ μ S E
where x ¯ = sample mean
μ = m e a n
t = 4 2 = 2
Option B is the right choice

Refer to the Journal of Experimental Social Psychology (Vol. 45, 2009) study of whether buying gifts truly buys love. Recall that study participants were randomly assigned to play the role of gift giver or gift receiver. Gift receivers were asked to provide the level of appreciation (measured on a 7-point scale where 1 = "not at all" and 7 = "to a great extent") they had for the last birthday gift they received from a loved one. Gift givers were asked to recall the last birthday gift they gave to a loved one and to provide the level of appreciation the loved one had for the gift. The researchers wanted to know if the average level of appreciation is higher for birthday gift givers than for birthday gift receivers. a. Why is this study designed? b. Specify the key elements of the study: experimental unit, response variable, factor, and treatments.

I am struggling with the following question:
A test is constructed to see if a coin is biased. It is tossed 10 times and if there are 10 heads, 9 heads, 1 head or 0 heads, it is declared to be biased. Can 20 be the significance level of this test?
My thinking is as follows: H 0 : p = 0.5
H 1 : p 0.5
Let X be the number of heads, under H 0 , X B(10,0.5).
If we look at a table of values, we get:
X=0,P=0.00098
X=1,P=0.0107
X=9,P=0.999
X=10,P=1
Since it is declared biased for these values, P<0.1 or P>0.9. Therefore, shouldn’t we be able to use 20% as the significance level, yet my book says we can’t. Any clarification?

We want to make an hypothesis test for the mean value μ of a normal population with known variance σ 2 = 13456, using a sample of size n = 100 that has sample mean value equal to 562.
Calculate the p-value.
Make the test with significance level 1 % about if the population mean value from which the sample comes from is greater than 530 using the p-value.
For the first one, about the p-value, do we have to calculate P ( 530 562 σ n ) ?
And for the second we have to check the p-value with the significance level, right?
