Question

Solve the following problem and give as an answer the LEFT limit of the confidence interval. Write up to two decimal places without rounding.

The anthropologist William Howells took data on cranial distances of remains found in Yauyos, Peru. One of the measurements is the distance between basion and bregma, denoted BBH, the data collected in his sample is shown below.

Mean: 122.43mm Std Deviation: 3.5159mm

The sample size is 101. finds a confidence interval for the variance of the BBH measure of the remains found in Yauyos with a confidence level of 90%.

a.We have two independent samples of
normal populations
1.The observed test statistic is 4.8 and at a
1% significance level we can accept the null
hypothesis.
and
N2W2,02)
with unknown parameters.
If we know that
X1 = 3.5, n = 10, sỉ=0.72, x2=3, n2 =11, s3=0.15.
b.We wish to prove that
2.The observed test statistic is equal to 1.77
and at a significance level of 1% we can
accept the null hypothesis.
then
We have two independent samples of
normal populations
and
N2(H2,02)
with unknown parameters.
If we know that
X1=3.5,
n =6, sỉ=0.72, X2=3, n2=10, s=0.15.
We wish to test whether population variance
one is greater than population variance two,
then:
c.We wish to test whether a measure that
the government intends to implement has
equal acceptance among women and men.
For this purpose, random samples of sizes
120 and 110 were taken respectively. It was
found that 70 women and 75 men
3.The observed test statistic is equal to 1.8
and at a significance level of 10% we reject
the null hypothesis.
responded in favor of such implementation.
Then
d.
4.The test statistic is observed to be equal
to 1.5576 and at a significance level of 10%
the null hypothesis is accepted.
If we know that
X1 = 3.3, n = 49, =0.75, X2= 3, n2 = 49, o = 0.25.
and we want to prove that
then
