Question

The display provided from technology available below results from using data for a smartphone? carrier's data speeds at airports to test the claim that they are from a population having a mean less than 5.00 Mbps. Conduct the hypothesis test using these results. Use a 0.05 significance level. Identify the null and alternative? hypotheses, test? statistic, P-value, and state the final conclusion that addresses the original claim. LOADING...

Upper H 0?: muequals5.00 Mbps Upper H 1?: mugreater than5.00 Mbps C. Upper H 0?: muequals5.00 Mbps Upper H 1?: munot equals5.00 Mbps D. Upper H 0?: muequals5.00 Mbps Upper H 1?: muless than5.00 Mbps Identify the test statistic. nothing ?(Round to two decimal places as? needed.) Identify the? P-value. nothing ?(Round to three decimal places as? needed.) State the final conclusion that addresses the original claim. ? Fail to reject Reject Upper H 0. There is ? not sufficient sufficient evidence to support the claim that the sample is from a population with a mean less than 5.00 Mbps. u<5.00 t=-2.708102 p=0.004646 x=4.42 Sx=1.514426 n=50

Answer 1

for null and alternative : option D is correct ; Ho: $\mu$ =5 ; Ha: $\mu$ <5

test statistic =-2.71

p value =0.005

Reject Ho;  There is sufficient evidence to support the claim that the sample is from a population with a mean less than 5.00 Mbps
