For the following problem, test the claim about the population mean u at the given level of significance using the given simple statistics. Be sure to list the following in this order.

Claim: u > 1030;

alpha level = 0.05;

Sample statistics:

Sample mean = 1035,

s.d. = 23

n = 50

**a) Null hypothesis: **** b) Alternative hypothesis: **** c) Calculated z score:**** d) Area corresponding to the z: **** e) P-value:**

**f) Decision whether to accept or reject Ho and at what % of confidence**

9. For the following problem, test the claim about the population mean u at the given level of significance a using the given sample statistics. Be sure to list the following in this order.

**a) Null hypothesis: Ho: **** b) Alternative hypothesis: **** c) Alpha level: **** d) Degrees of freedom: **** e) Table t-value from Table F: **** f) Calculated t value: **** g) Decision whether to accept or reject Ho and at what % of confidence**

Claim: u > 25,

alpha level = 0.05;

Sample statistics:

Sample mean = 26.2,

s.d. = 2.32,

n = 17

10. For the following problem, determine whether or not to accept or reject the null hypothesis. Be sure to list the following in this order.

**a) Null hypothesis: **** b) Alternative hypothesis : **** c) Alpha level: **** d) Whether or not it is a one tailed or 2 tailed test: **** e) Table z value : Z(0.025) = **** f) Difference between x1 and x2:**** g) Calculated z value: **** h) Decision whether to accept or reject H0**

Claim: u1 ≠ u2; alpha = 0.05.

Statistics

X1 = 52 X2 = 45

s1 = 2.5 s2 = 5.5

n1 = 70 n2 = 60
