Blood pressure: High blood pressure has been identified as a risk factor for heart attacks and strokes. The proportion of U.S. a
telo118 [61]

Answer:

Yes it appropriate to use the normal approximation to find the probability that more than 43% of the people in the sample have high blood pressure

Step-by-step explanation:

From the question we are told that

The population proportion is  p=0.4

  The sample size is  n =  39

  The sample proportion is  \^ p = 0.43

Generally for normal approximation to be used

       np > 10

so np  =  39 * 0.4 =  15.6 > 10

   and n(1- p) >  10

so   n(1-p ) = 39(1-0.4) = 23.4 >10

Given that the both condition is meet it mean that  it appropriate to use the normal approximation to find the probability that more than 43% of the people in the sample have high blood pressure

9. An automobile dealer believes that the average cost of accessories in new automobiles is $3,000 over the base sticker price.
aliya0001 [1]

Answer:

There is no enough evidence to claim that the average cost of accesories is different from $3,000.

Step-by-step explanation:

<em>The significance level for this test is α=0.05.</em>

The classical method is based on regions of rejection of acceptance, according to the sample parameter. In this case, the standard deviation of the population is unknown.

The null and alternative hypothesis are:

H_0: \mu=3000\\\\ H_a: \mu\neq 3000

This is a two-tailed test, with significance level of 0.05.

The t-value for this sample is:

t=\frac{x-\mu}{s/\sqrt{N}} =\frac{3256-3000}{2300/\sqrt{50}}=\frac{256}{325}=0.787

The degrees of freedom are:

df=n-1=50-1=49

For df=49 and α=0.05 (two-tailed test), the critical values are |t|>2.009, so the value t=0.787 is within the acceptance region.

The null hypothesis can not be rejected.
