a)
p = 1/2
b)
p^ = 22/32
c)
q^ = 1 - 22/32 = 10/32
d)
np = 22 > 5
nq = 10 > 5
hence normal approximation is valid
e)
Z = (p^ -p)/sqrt(pq/n))
= (22/32 - 0.5)/sqrt(0.5*0.5/32))
= 2.12132
f)
claim : proportion of choosing red rattle is 1/2
g)
proportion of choosing red rattle is not 1/2
h)
Ho: p= 1/2
Ha: p not equal 1/2
i)
p-value = 2 P(Z >2.12132)
= 2*0.0169
=0.0338
m)
p-value < 0.05
we reject the null hypothesis , we conclude that p is not equal to 1/2

Do Babies Understand Probability? Can babies reason probabilistically? A study investigates this by showing ten-to twelve-month-old infants two jars of lollipop shaped objects colored pink or black. Each infant first crawled or walked to whichever color they wanted, determining their "preferred" color. They were then given the choice between two jars that had the same number of preferred objects, but that differed in their probability of getting the preferred color; each jar had 12 in the preferred color and either...
Returning to the same study examining the relationship between maternal smoking during pregnancy and congenital malformations (among children who suffer from an abnormality other than Down's Syndrome or an oral cleft, 32.8% have mothers who smoked during pregnancy), consider children born with an oral cleft. In a random sample of 27 such infants, 15 have mothers who smoked during pregnancy. a) What is a point estimate for p? Construct a 95% confidence interval for the population proportion. b) Conduct the...
A study followed 20 infants to find out when they speak their first word of English (in an English-speaking household). They found that the children were 13 months old on average when they spoke their first word; the data had a standard deviation of 4.93 months. What is the average age at which the population of children speak their first English word? First answer each of these questions: i) Does this call for a confidence interval or a hypothesis test?...
