Records on a fleet of trucks reveal that the average life of a set of spark plugs is normally distributed with a mean of 22,100
fgiga [73]

Answer:

There no sufficient evidence to support the manufactures claim at the 0.05 level

Step-by-step explanation:

From the question we are told that

   The  mean is  \mu  =  22100 \ miles

    The  sample mean is \= x  =  23400 \ miles

   The  sample size is  n  = 18

   The standard deviation is \sigma  =  1 500 miles

    The test statistics is  t = 3.677

    The level of significance is \alpha  =  0.05

The null hypothesis  is  H_o :  \mu =  22100

The  alternative hypothesis  is  H_a :  \mu  \ne 22100

Generally the p-value  is mathematically represented as

     p-value  =  2 *  P(t >3.677 )

From the z-table  P(t >3.677 )  =  0.000118

So

    p-value  =  2 *  0.000118

=> p-value  =  0.000236

From he value given and obtained we see that  p-value  <  \alpha

Hence we reject the null hypothesis

Hence there no sufficient evidence to support the manufactures claim
