A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are $n = 195$, $\bar{x} = 7.59$, $s = 1.87$. Use a 0.01 significance level to test the claim that the population mean of such ratings is less than 8.00. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses? A. $H_0: \mu = 8.00$ $H_1: \mu < 8.00$ C. $H_0: \mu < 8.00$ $H_1: \mu > 8.00$ B. $H_0: \mu = 8.00$ $H_1: \mu \ne 8.00$ D. $H_0: \mu = 8.00$ $H_1: \mu > 8.00$ Determine the test statistic. (Round to two decimal places as needed.)

For the following configuration the BJT (NPN) has a common, emitter current gain B=150. (A) Determine the DC biasing current $I_{Bias}$, so that the intrinsic voltage gain of the circuit $A_{vint} = V_{be}$ = 46 dB. What is the DC voltage at B and C, then? (B) If the capacitance of $C_B$ and $C_C$ are great enough, so that their impedances can be neglected, design $C_E$, so that the circuit has a low cutoff frequency of 50 Hz. $V_{CC} = 15V$ $R_C = 30k$ $C_C$ $R_{sig}$ $C_B$ $3k$ $R_{BB}$ $100k$ $V_{sig}$ $I_{bias}$ $C_E$ $R_L = 30k$
