The accompanying table lists the numbers of words spoken in a day by each member of 58 different randomly selected couples. Complete parts (a) and (b) below. E Click the icon to view the data on words spoken in a day by the couples. a. Use a 0.05 significance level to test the claim that among couples, males speak fewer words in a day than females. In this example, e is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the words spoken by the male minus words spoken by the female. What are the null and alternative hypotheses for the hypothesis test? Ho: word(s) H: word(s) (Type integers or decimals. Do not round.) Identify the test statistic. t= (Round to two decimal places as needed.) Identify the Pvalue. P-value =O (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? Since the P-value V the significance level, V the null hypothesis. There sufficient evidence to support the claim that males speak fewer words in a day than females.

Transcribed Image Text:The accompanying table lists the numbers of words spoken in a day by each member of 58 different randomly selected couples. Complete parts (a) and (b) below.
E Click the icon to view the data on words spoken in a day by the couples.
a. Use a 0.05 significance level to test the claim that among couples, males speak fewer words in a day than females.
In this example, e is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the words spoken by the male minus words spoken by the female. What are the null and alternative hypotheses for the hypothesis test?
Ho: word(s)
H: word(s)
(Type integers or decimals. Do not round.)
Identify the test statistic.
t= (Round to two decimal places as needed.)
Identify the Pvalue.
P-value =O (Round to three decimal places as needed.)
What is the conclusion based on the hypothesis test?
Since the P-value
V the significance level,
V the null hypothesis. There
sufficient evidence to support the claim that males speak fewer words in a day than females.
