Question

I posted a similar question earlier and the person who answered it was wrong.

8.8.50 A maker of a certain brand of low-fat cereal bars claims that the average saturated fat content is 0.1 gram In a random sample of 8 cereal bars of this brand, the saturated fat content was as shown belo 0.4 0.5 0.3 0.2 0.5 0.8 0.3 0.4 Would you agree with the claim? Assume a normal distribution Click here to view page 1 of the table of critical values of the tdistribution The computed tvalue is t so P(T is between Q.10 and 0.15 This does not provide evidence to disagree (Round to two decimal places as needed.) bn 0.15 and 0.20 ess than 0.01 greater than 0.40 between 0.10 and 0.15 between 0 20 and 0.30. between 0.30 and 0 40

Answer 1

The statistical software output for this problem is:

One sample T hypothesis test:
? : Mean of variable
H₀ : ? = 0.1
H_A : ? > 0.1

Hypothesis test results:

Variable	Sample Mean	Std. Err.	DF	T-Stat	P-value
Data	0.425	0.064779847	7	5.0169924	0.0008

Hence,

Computed t - value = 5.02

P(T > t) is less than 0.01

This provide evidence to disagree.
